This has happened to me as well, usually it is just an error at the end of the night when they do the "close drawer' Sometimes the server makes an error. Here is what you do;
1. inform your bank that it is an error, and to suspend the funds to the establishment until they can submit the slip for verification.
2. Ask your boyfriend to lend you enough money to cover your expenses until this is fixed.
3. FInd a boyfriend who does not make you pay for a date… seriously!
