Double drop

The double drop is a scam that uses while working at a neighborhood bar and grill in "The Gang Sells Out".

How it works
Dee prints out two receipts for the same ticket, and gives them to two different tables. She legitimately charges one check and pockets the other table's money.

Dennis tells Dee that The Gang is aware that she has been doing this, and they always used to take the amount she double-drops out of her purse.
