If you are playing table games, you go to the cashier and he/she will give you promotional chips (for non-refundable OBC). When you win at the table, you will be given "real" chips. We play Black Jack and most of the time we are able to covert the majority of our non-refundable OBC into cash. When you are done playing, take the "real" chips to the cashier and he/she will give you cash.
