xconcepx,

Taking back the $50 was poor form on your part. You gave it to her and that should have been the end of it. Do you take back Xmas presents if the receiver doesn't later do what you want?

Sorry you had a dud punt, but that's the name of the game... Punting.

Maybe in the future you don't 'tip' until you know what you're tipping for.
