I'll bet a lot of you are. So here's the quiz; A few weeks back we're at Caesars AC ,Mrs. is playing VP,I'm sitting at machine next to her trying to get it to accept a 20. No dice so I walked around and grabbed an attendant,he pulled the cover ,checked out the machine and was baffled so he called a tech with tools. He did the same thing ,still not working when finally he figured out the problem. So what was the simple answer?
