In reply to Tim Chappell:
> Personally I make a point of treating waiters and those in similar jobs as human beings. And I think it really *is* rude not to, no matter what the local mores. They're not machines, you've got to acknowledge them.
> What annoyed my daughter, when she was waitressing whilst at Uni, is that ( some) people talked down to her, and treated her as if she was stupid because she was serving them.
( she was a Maths & Physics student, and very possibly brighter than most of those that talked down to her) But that apart it IS only good manners to be polite.
( and by the way , waiting staff pretend not to hear people who snap their fingers, and I would not recommend doing it, they ARE serving you food after all, so not a good idea to annoy them)
So Tim, I agree with you, I make a point, when working late, to take time to chat to the cleaners, and I am embarrassed, at those colleagues who will totally ignore them as they try to clean around them.
