This is very common especially if you typically play during the afternoons or late at night when it is slow. There are a ton of little scams employees run. Free drinks === bigger tips, etc. It's not right but it does happen a lot. Chris knows this all to well I am sure.
Having had employees myself I have seen a bunch of scams. Had a service station on the rich side of town. Minimum wage was a buck and a quarter an hour and standard wages for pumping gas. My night shift guy was changing the air in all four tires when it got lumpy so the car would ride better. Charged two bucks for all four. I found out when a lady came by and told me how wonderful the car rode after him changing the air. Tried to get Tony to stop with this and a few more scams. Couldn't do it so although I liked him he was the first man I ever fired!
I could just bet that some people were getting "deals" at the side gate from my employees when I had an auto salvage. I had a four feet by four feet "Do not enter" sign there. The side gate was a drive in gate with a 22x24 feet shop building next to it. I had a doberman under my desk that had flunked police training, he had a few interesting habits. He did know about the side gate though. He would go sailing out from under the desk and seconds later you would hear him working. Some cries for help too. Any video of a police dog stopping somebody in place is the same. It looks like they are an instant away from tearing someone to shreds. If I was waiting on somebody I would ignore it for a few minutes or as long as five. When customers would ask if I needed to take care of that, "naah, he isn't going anywhere!" Happened several times a week at first, got down to several times a month. I'm sure the time against the wall before I came to peel them off was a long long time for the people!
Lots of employee scams. I had to fire a few men I really didn't want to over them. Some were stealing from me, some from the customers! I was over at a friend's auto salvage. A customer wanted to know what he would sell the tires on a car for. "I'll take ten apiece or fifty for the set!" The customer bought the set.
I waited until after the customer left. "Roger, you just charged the customer extra to buy the set of tires. "I know, Brother(one of his hands) did it and the customer was happy so we have been doing it ever since." All I could do was shake my head and laugh, it wasn't a practice I took up.
