51. Sweet Revenge
I worked as a cashier at a grocery store, and whenever someone would buy setting like baby formula or something, I would remove the little stuck-on security tag without deactivating it.
Whenever I would have a rude customer, I’d reach into my stash of tags and stick one onto something of theirs so that when they walked out the door alarm thing would activate.
Watching them get flustered when everyone would look at them was a nice feeling.
