if you work in retail whats the craziest thing you've seen/heard that a customer did?

I work at a grocery store. this one time this guy who was high on something came in and wrecked our produce section. he knocked everything over and was jumping on top of stuff. the cops came and he apparently threw a watermelon at them lol. unfortunately I was off that day so I only heard about it. I wish I would have been there to see it
