I agree that general standards and politeness have definitely declined, but, I think, on this thread, that we're losing sight of the fact that you work in a customer service industry and it's the customers that do, in fact, pay your wages.
Well here's a point that we had to point out to our Managers at a certain airport for a certain handling company: -------
"Without the passengers, we would not have a job.
Without the Pax service agents they would not have a holiday"
Should not we all be pleasent to each other???
