I was working at a video store -- this was about 1999 or so, when they still had VHS tapes -- and we had a program with our popular new releases that if we didn't certain titles in stock, we'd give you a coupon for a freebie for next time. This usually applied toward big-name movies, or "Blockbuster" titles, if you will.
One night was especially busy, and we were all out of one movie, and so we were handing out coupons left and right. (I don't even the remember the movie, which I should if I'm going to continue harboring resentment toward the incident.)
We did keep a small stockpile of these movies behind the counter, because we found out that people were coming around with no intention of renting the movie in question, just to get the free coupon. There was nothing more priceless than having some asshole come up to the counter saying, "You don't have any copies of ________, so I'll take a coupon." I would say, "Well actually, it's your lucky day!" and then produce a copy of the movie. More than a few times, the person would say, "Oh, no never mind," and I would leave a comment on their account not to give them any coupons or refund them any late fees for trying to scam. Ah, the good old days.
So anyway, this one guy comes up to get a coupon, and so I gave one. We were completely out of copies, even our backups. The kid didn't look like white trash: he was relatively well-dressed, nice-looking enough (no homo) and if I didn't know better I would have assumed he was not a piece of shit.
I gave him a coupon and dated it one month later to the day, which was the policy. Since we were so busy, I forgot about the kid and started ringing up other customers. The video store I used to work at did a ton of business, and Friday nights were often out the door.
About ten minutes later, the kid to whom I had just given the coupon for the freebie (to be redeemed at a later time) came up with the movie that we had been out of, and so he plopped that and the coupon on the counter, smiling a sketchy little smile as if to say, "Give my my free movie, bitch."
I was pissed for two reasons:
1) It turns out that this sonofabitch went into our "Employees Only" video drop box and found the movie he was looking for. (We didn't have a lock on it, and at this store it was out on the floor, not behind the counter.) He went into an Employees-only space, like a selfish hunk of shit, and just took what he wanted. Make no mistake, this was a violation. Since I had already given him the coupon -- and didn't wait until he left the store as I had been instructed to do by my manager -- I had no recourse. And the reason I had no recourse was ...
2) ...because I never put a date range on the ticket. I gave an end-date, but I never gave a beginning date. (From this point forward I would always put the next day's date on the ticket.) I still don't know whether I was furious at myself or at the scheming piece of trash who did this.
The worst part is, I'm sure he doesn't remember the incident. Even worse, I couldn't pick him out of a lineup, which means the odds of me identifying him well enough to punch him in the testicles gets slimmer by the day.
