DEAR MISS MANNERS: When an eyewitness is interviewed on television or radio news accounts, invariably the news anchor will finish the conversation with a "Thank you."

I realize that the appropriate response should be "You're welcome," but when the story is tragic in nature, that seem inappropriate somehow, almost undercutting the seriousness of the situation.

Usually the witness (or field reporter) mumbles something inarticulate or simply nods his head. In other languages, saying "At your service" works well, but in English it comes off as far too formal. A few try "Of course," but that seems almost rude.

Is there some better way of responding, something that doesn't jar, that recognizes the anchor's thanks without trivializing the incident?

GENTLE READER: Even so-called guests on the air --experts there to give their analyses or opinions -- find this awkward, because one wants to give the usual response to "Thank you." Yet their "Thank you for having me" wouldn't do at all under the circumstances you describe.

Witnesses to tragedy are more like temporary news correspondents, although they could hardly adopt the response of "Now back to you." They can be said to be doing their duty to report what they know, and Miss Manners sees nothing rude about their responding with "Of course" or "Certainly," or even a simple serious nod.

DEAR MISS MANNERS: Granted, I have a large collection of friends, acquaintances and admirers. Therefore, I am often invited to dinner parties, gallery openings, etc.

I enjoy being social. And I really enjoy being alone and reading -- my favorite pastime.

Often, when I refuse an invitation, the inviter will ask what I will be doing instead. Well, this Thanksgiving I have been invited to three homes, but I am interested in staying home and making a meal for myself. As a single person, I have been going to people's homes for holiday meals for decades; it is no longer interesting.

Upon being told that I was not coming to their home for Thanksgiving, all three were highly insulted that I wanted to be alone rather than with them. In other words, why would one want to be alone when we are here to be enjoyed? Should I have lied?

GENTLE READER: No, but you needn't have explained that you prefer no company to theirs. Are you surprised that they were insulted?

Of course, would-be hosts have no business probing for your plans, which is not only rude but also dangerous. Still, they were trying to be hospitable, and they are, as you say, your friends, acquaintances and admirers.

Miss Manners recommends your saying, "You are so kind to think of me, but I have my own little holiday rituals. Let's get together another time." And she would hope they would leave it at that and not make you respond coyly to further questioning with, "Well, if I told you, they wouldn't be private."

DEAR MISS MANNERS: Would it be impolite to bring a favorite condiment to a dinner gathering, knowing that the hosts do not have that particular one?

GENTLE READER: Only if you want to make it clear that you consider their offerings to be lacking taste.

After 10 minutes of guessing among ambiguous voicemail menu choices, a caller is connected with someone who cannot solve his problem -- and who insists on putting him back into voicemail. Neither of them knows that the computer is systematically (and unfeelingly) routing people with billing questions to Children's Clothing.

A customer who gets to the front of the checkout line and finds the clerk on the phone is angry that he is not being served. She is unaware that the clerk is required to do double duty answering the company telephone.

An airline passenger who asks a question of the person behind the desk at the gate is annoyed to be told that he will have to wait for a different employee who might know the answer. He has not realized that the person at the computer is a pilot, not a gate agent.

The employees are just as frustrated as the customers:

"If this guy wanted a giraffe onesie for his daughter, I could help him. But why is he yelling at me about a billing problem?"

"I'm wearing a company headset and answered the phone by saying, 'Enormous Corporate Chain, how may I help you?' Isn't it obvious that I am waiting on another customer, not chatting with my boyfriend?"

"I'm a pilot with 20 years of experience, and I'm wearing my hat. I'm using this computer to get a flight plan so I can fly this passenger quickly and safely to his next destination. Why does he expect me to know how many points he needs to qualify for Agate Geode Status?"

Who was at fault? Everyone.

Someone not present at the eventual blowup has created a situation in which misunderstanding is certain to occur. The checkout person, the sales clerk and the pilot have been made to look rude by a badly programmed voicemail system, an unfortunate assignment of duties and the placement of a computer.

So the customer has taken offense and turned aggressive. And the employee has responded in kind.

They have Miss Manners' sympathy, if not her approbation. But as everyone has misbehaved, everyone can help Miss Manners clean up the mess.

Corporate America -- and any consultants paid to think for it -- needs to finish what it starts. After what feels like a lifetime on computer support, Miss Manners understands what happens when a technician "fixes" a computer problem, but fails to verify the result. People designing airports, programming voicemail systems and making duty assignments need to think through how these will be used.

The same is true of everyone else involved in decisions that will affect what we now call "the customer experience."

The employee needs to remember that he or she represents the company, for good or ill. It is necessary to be prepared for the possibility that the customer has already had reason to be frustrated, and to be able to defuse the situation with an apology and a solution.

"My apologies, you were routed to the wrong department, but I can get you to the correct one. And let me give you the direct extension for that department in case voicemail fails again."

"Forgive me, I have a telephone customer, but you are next."

"I'm sorry, but I'm the pilot and am not trained in gate operations. This station will open 30 minutes before your flight, when someone will be able to help you."

The customer must accept the apology gracefully, if not, perhaps, gratefully, and employee and customer should both consider contacting corporate headquarters to give them a chance to correct the original mistake.

Meanwhile, Miss Manners will attempt to decipher the corporate website, which is forcing her to choose among "Plan My Visit," "Enhance My Experience," "What's Happening," "Information" and "Help." She doubts that any choice will live up to its title.

DEAR MISS MANNERS: My dear friend of 40 years has a husband who is recently disabled and who now uses a handicapped parking placard that hangs from his rearview mirror.

When out together as couples, we have been dismayed to find that there are no handicapped spaces available at the restaurant or theater. We have all commiserated on what we feel is an abuse of handicapped spaces by the able-bodied.

Recently I drove this friend and two other friends to a garden/museum for what was to be an afternoon ladies' outing. As we drove by the handicapped spaces, my friend remarked, "It's a shame that I didn't bring hubby's placard in my purse -- we could have parked in a handicapped space."

I was shocked/disturbed by this comment and replied, "No, we would NOT have parked in a handicapped spot!"

Her response was, "That's ridiculous -- there are a hundred empty spaces!" (Obviously, an exaggeration.)

I then said, "I am sorry, but I don't care to be part of the problem."

My friend did drop the subject, but I wondered if there might have been a better way for me to have handled this.

GENTLE READER: Probably. What you said was justified, but Miss Manners fears that it is the way you said it that might have caused offense.

Perhaps something more along the lines of, "Surely, you do not want to contribute to the abuse of handicapped spaces that is causing this problem in the first place," would have resonated more deeply with your friend than being more severely reprimanded.

DEAR MISS MANNERS: For many years, I frequently have had people come up to me in public places and say, "How do I know you?" or "Where do I know you from?" or "Haven't we met before?"

This is not a "pickup" line -- it happens with both males and females all the time.

I typically respond that I have a familiar face and people say this to me all the time. As I have gotten much older, I thought it would subside, but it has not. I don't mind to some extent, but it's gotten to the point that some people will not let it drop. They are insistent on trying to figure out who I am or where they may have met me before.

I always try to be as friendly and jovial as possible, but am not sure how to handle it when they keep coming back to me to try to figure it out. This typically occurs when I am out with my husband or friends for the evening, and we are all just trying to visit with one another over dinner, coffee or drinks, etc.

I've even had people sit down at my table and start asking me very personal questions so they can try to determine where they have met me before.

Do you have any suggestions?

GENTLE READER: "You probably saw me in my high school play."
