it doesn't hurt to go the extra mile when dealing with people. The counter guy is rude to you? Wait. Think. Maybe he just got some bad news. Maybe he's not getting that much needed and deserved raise. There is always a back story to peoples' rudeness. This does not excuse his behavior but merely puts a reason to it. I had a really nasty woman wait on me at walmart. I mean she was one second from being reported to the manager. I asked her right to her face-"why are you being so mean to me? You're being extremely rude for no reason. I'm a customer here trying to pay for my items." She stopped and looked at me and I said "I like your nail color". A small kindness. We've been talking since. When I see her at Walmart we always chat. She apologized for her bad behavior that day. I always try to be as polite as possible-even though some people can stretch my patience. A simple thank you always works.
