In general, I think most posters act in a genuine and sincere way.
Many are coming for the first time.

It is part and parcel of providing a Help Desk service that not every
question will be interesting, fresh, etc.

I think we should all just comment when we want to and when we do, in
a way that will be most helpful.

Sometimes that means leaving the question for someone else to answer.

Sometimes it means responding with something like:-

But I don't think it serves any good purpose to "tell them off".

I once took my car to a tyre-fitter and said "I have a nail in the
tyre of one of my back wheels, not sure which.  Can you repair or
replace it?"

The mechanic was very rude because he could not believe that I could
not remember if it was on the left or the right.

I did not feel like a "cared for customer"!

And how many times have you been to a supermarket/store and asked an
assistant "Which shelf is the ... on?" only to be told that it's right
behind you or you just walked past it?
