Well, this isn't quite what you guys were meaning, but, as a Taco Bell employee, I've seen people do some weird s*** to their food in order to get free stuff.
DON'T TRY THIS STUFF YOURSELVES!!! IF YOU DO, I SHALL HARVEST YOUR SOUL AND FEED TO JIGGLYPUFF!!!
This guy went through drive-thru and ordered a grande meal; I don't rememberthe exact proportions, but it had some burritos. Anyway, he came into the store with a partially eaten burrito and said that it had stuff in it. What was the stuff? Pocket lint! You could tell by looking at it that it had just been put there. It wasn't covered in beans, it didn't look "warm" from being wrapped up in the burrito, and how in the heck would it have gotten in there to begin with?
Instead of giving him a "hassle" he was refunded for the one burrito. It didn't please him, because he wanted back. However, he didn't show us the rest. Maybe next time he'll honor the awesome pricing of $7.90 for ten burritos. Why would someone want to rip people off who provide such a nice discount package? People like that need to be sent to jail, I think. Better yet,we should be given monetary compensation, because his act of stupidity and greed cost us time that should have been invested in making other people's food, people who were actually worthy of service.
