Water Fight
I was a shift manager at Taco Bell in high school. My most memorable moment was when I was working the drive thru window. Some guys ordered some tacos or whatever, and when they pulled up, I noticed they were a few feet back from the window (they didn’t pull far enough forward.)
I opened the window to say something, and immediately get drenched in windshield wiper fluid. These jackals rotated their nozzles for this and ensured they were properly lined up. They were.
I was angry, and threw a large pop at them as they were peeling out, which landed inside the window. I think I won. Story credit: Reddit / TheNightOwl
