#8: Keep the Change
Few people carry around cash anymore, but when we do, we rarely have the exact amount to purchase without receiving any change. So, watching show after show after show is a bit unrealistic, where no extra charge is returned to the purchase. The cash register opens, but nothing comes out.

While “keep the change” is definitely a possibility, we highly doubt it is something that happens in every single transaction. This only leads us to believe that it’s designed to make the scene easier to carry out. Honestly, who can afford to lose that much money these days?
