Hours vs pay, expectations of a job that's basically like card counting except chips. They expect you to be able to do VERY fast mental math without aids. Basically you sit on card games on keep a count and watchful eye on all players and dealers. You are a 3rd party that's not very welcome.
Is keeping track of several players several payouts and your own chip pile easy? Heck no. Can you constantly calculate within seconds 1.2 times 35? 35*125? 150*270? all day?
Then also understand complex card games, working in the middle of the night or anytime of the day? Its not worth 17 or 15 an hour! I have working a long time in accounting and can follow a lot of complex operations and calculations on my own with and without a calculator but this is ridiculous.
