At the last place I worked, we unfortunately encouraged ushers to do whatever they could to get as much money as they could. Why? Because the theaters that collect the most get special bonuses, or some other sort of incentives (I forget what exactly). So, some of our staff became quite aggressive with the customers in asking for their coin. They’d make remarks behind the backs of people who didn’t give, for instance, or otherwise attempt to make non-givers feel guilty in some way.
