My guess. Drunk idiot leaves $1000 tip to the pretty waitress. Card processor declines as being way out of the ordinary. Meanwhile, drunk idiot gets home and the ball and chain finds out about the $1000 tip and all hell breaks loose. Has “second thoughts” among screeches of HALF! REEEEEE! HALF! In the end both the waitress and the owner got trolled in a rather cruel way.
Did he write 2000 or 20.00 or 2000.00?
