The world could use a little more politeness. Please, thank you etc. If you are wearing a name tag or you tell me your name, I will make sure I use it. Especially when dealing with a service. (phone rep, server, cashier any person that is doing a service for me) I have always found I get better service when I make a personal connection by using a person's name. "may I take your order" Yes, thank you, Mary. Not that hard to do.
