of 29 casinos in Vegas area in one day. Wife would wait in car near front entrance and I'd run in and harvest a dozen current 5.00 & 1.00 chips or tokens. It was 106 out side at the time. That was the first and last time I did that trick. Now with the traffic and size of some hotel/casinos what a job. I have a lot of respect the NIS in Vegas. Good luck!
