So being 19, what category do I fall into?

Anyways, it was engrained (sp?) into me as since I was a kid that when someone says "Thank You" you respond with "You're Welcome." Nothing lowers a waitor/waitress's tip faster than responding with "No Problem."

It also gripes my aiss when someonen says "Here you Go." I've resorted to responding with "Here I am", but most people still dont get it.

That's my .02 for anyone that thinks that no young person has any manners.
