No matter what else you might think, the "Customer" is NOT always right! Go ahead, be a MAN and say it. People who work in the Technology industries know that users are Cry Babies and techo-illiterates. Anyone that uses a CD Rom tray for a coffee cup holder is an absolute techno-useless person. When they can't figure out what's wrong and you point out that they haven't plugged the unit into the power socket, they are at a real disadvantage.

Although it is our job to "please" the customer, it is also our job to point out the obvious with some tact and humble demeanor. We must EDUCATE the ILLITERATE, not chastise them for their ignorance and stupidity.
