Big Mac Murder
I used to work at Burger King and at one point I was watching the register while the manager was doing inventory and this guy came in and tried to order a Big Mac.
When I told him we didn’t sell Big Macs because it was a Burger King he went nuclear and threatened to follow me home and shoot me in front of my family because I wouldn’t give him a Big Mac. Story credit: Reddit / 3vilR0ll0
