Yup Mmario, it pays to be polite as long as you can possibly stand it, even if you don't feel its deserved ...I work in a hardware store and very frequently people quiz me in detail about some tiny little thing that they're trying to figure out how to do. In a lot of cases I could say "I don't know" cause I often don't, but I make a point of trying to help them find the right little widget, asking enough questions so I know what they're trying to do rather than just what they think they need, and offering additional tips if they look like they need it. Now a lot of times I'm doing this while thinking "sheeez, that's a dumb question and I've already answered it three times", but almost always, whether or not we find what they need, they end up thanking me for good service. Which puts a whole different character on the exchange for me. People are nice, if you give them enough slack. Routine politeness takes awhile to come back to people who have forgotten the habit--but it usually does.
