I did something like that a bazillion years ago. I poured hot coffee on the offender’s crotch. Left the room without a word. Told my boss I was leaving for the day, and if he wanted to know more, he should ask my coworkers.
When I returned two days later, I was apologized to, and we all got back to work. No one ever tried to mess with me like that again.
You GO, Girl! :)
