Okay so you have all heard stories about ridiculous customers...I think it's time for a co-worker story.
At McDonald's, we have what is called a "tea cart," which is obviously used to fill up the tea containers.  One day my manager asked one of my co-workers to go fill up the tea in the lobby.  This young man (who shall remain nameless), takes the tea cart out to the lobby, whips it around the corner and spills it ALL OVER THE FLOOR.  This is a cart that has individual tubs of tea, and every one of them was filled up.  I mean, the tea covered the ground all the way from the front counter, to the back door.  Surprisingly my manager wasn't angry at all, but told him to go get the store vacuum from the shed.  I kid you not he comes back with a LEAF BLOWER and asks if that is the store vac.  Let's just say I'm pretty sure everyone in grill peed their pants laughing, and the guys will never let him live that down.
