some people are such jerks

At work, we have coupons; people buy 20 dollars' worth of tickets for the slot machines (this is a coinless casino, tickets and bills only), and the cashier gives them two dollars free, giving the customer $22 in tickets. The whole point of these tickets is to get people to play the machines, 'cause we know we're going to get the $2 back (most likely), which is why we give the customers tickets, not cash.

I have a customer and his wife, each recieving $22 in tickets, two $10 tickets, and two $1 tickets. Most people will just try to shove the whole wad of it back at me and say, "Okay, I'd like to cash this in now," to which I reply, "I'm sorry, it doesn't work that way, you need to play them." In all reality, the people could walk around a corner, stuff all four tickets into a machine, and come back to me with a $22 ticket that I would happily cash in for them. At least then it looks like they have attempted to gamble.

So I give the tickets to the customer and his wife, except he takes all of them, sorts out the $10s from the $1s, and gives me back the $10s, saying he wants to cash them out.

Me: I'm sorry, but it doesn't work that way, you need to play the tickets.
PI: They just gave me cash for them last time.
Me: Well, they're not supposed to.
PI: But they did.
Me: I'm sorry, sir, they're not supposed to do that.
PI: Well, I'm a Private Investigator, and I know the Owners, Dad and Son* and-
Me: Yessir, I know who they are. (Thinking: Everyone knows the Owners in this town.)
PI: I'm telling you this: if you don't do this for me, I'm going to talk to the Owners.
Me: Sir, I can't give you cash for these. The whole point of these coupons is to BUY 20 dollars' worth in tickets, and I give you back two dollars free. When people see that I have given you cash, when these aren't redeemable for cash, they're going to want to do that, and everyone is going to want to do that. If people start taking advantage of this, we're not going to be able to do coupons as much anymore.

At this point, I had already given him back his $40 in cash because I didn't want an argument from the so-called private investigator (in a wheelchair, btw), and because I was tired of arguing with him.

And it's strange that he gave back the $10s instead of the $1s, because most people want to get the "free" money back in cash, so they can just take off with it or whatever they do. He was a real jackass, though, and only threw in the whole "private investigator" crap to intimidate me. What is he going to do? See how many speeding tickets I've recieved? Jerk.
