When karma catches up to you
This is a pretty brief story that undoubtedly ends in heartbreak. The OP was on duty when a woman and her kid entered the restaurant. Don’t worry, this isn’t a story about some misbehaving kid running into dinner tables and ruining everyone’s night. It’s much worse than that.
It turned out that her husband was also at the same restaurant, but he wasn’t dining with his wife and son. Instead, he was there with his mistress. The OP didn’t explain what happened next, but we’ll fill in the blanks for you. She poured wine all over her soon-to-be-ex-husband and left the restaurant to file for divorce.
