I get Christmas tips from a few clients. An employee or two has been tipped 20.00 for speedy fixes. Not on the retail side,but on the business side.
I don't have any clients who tip me outright, but one of the attorney's I work for has been known to give me free legal advice and another client frequently gives me free UPS and FedEx shipping.
Yes, Mr. Death... I'll play you a game! But not CHESS !!! BAH... FOOEY! My game is... WIFFLEBALL!
