The General
Another Day, Another Dollar
I copy every wager I make along with a screen shot of my balance to a word doc in case of a mis-grade or tech error. I highly suggest you do so also so that you have some evidence if there is a grading error. If you do not have a copy of your ticket number then you cannot argue if a wager would happen to disappear which happens sometimes. Technical issues would be the main reason IMO and not outright deception.
