Stealing From McDonalds

If you complain about mayo on your burger, they make them too. Because, you know, scraping it off is way harder than getting a new one. Seriously though, any shitty job like that, or retail, if you bitch enough, the store will cave. Not because you're right, but just because they don't get paid enough to care.

They may very well have all of your names from scanning your cards, good luck.

Even so, it's a mis, and you could argue you thought they gave you the food cuz you thought your card ended up working.
