We ordered pizza for delivery tonight, and I ordered it online and paid with a credit card.  Usually when I do that, I do not put the tip to the credit card -- I give the tip at the door in cash, because I think it's nicer that way.  But tonight I didn't have any small bills, so I added the tip to the credit card.

And tonight's lesson was: You should not add the tip to the credit card because it is quite possible that, by the time the pizza is delivered, the delivery guy does not deserve as much tip as you put on the card...
