From what they tell us, a large chunk of the money goes to charities anyway so that's fine by me. At least when I put my money in, I know that it's not like a casino where they are the only ones lining their pockets. ...
A couple of weeks ago I was a volunteer at a casino for my kid's school. Every school in the area gets two days once a year where they provide volunteer parents and teachers, and in return the school gets back a % of the take. A couple of years ago they received $11,000 for school supplies as they saw fit.
My wife worked as a chip-runner, and says she must have carried $250,000 during the day. I worked the late shift from 10pm-3am in the count room, where I opened up the boxes and layed out the money on the table, where others counted and re-counted (with machines). One box had 190 x $100 bills in it. We counted $240,000 that night.
It was worth doing for the school. I can see why it benefits the casinos as well because the volunteer jobs were the ones you had more direct contact with the money, and long-term employees are more likely to get tempted. This way, volunteers are just having fun, and they aren't interested in trying to swipe any cash because they don't know the casino security procedures.
