We had a couple who would come in regularly and always asked to be seated in my coworker’s section. They were probably in their 60s and were always really affectionate and cute with each other. My coworker would joke around with them all the time.
One day the man came in with a different woman than usual, and my coworker jokingly told him “ooooh, you’re in trouble. I’m going to tell your wife you were here with another woman.”
Woman said “Excuse me? I am his wife. Who the fuck has he been coming here with?” Dead awkward silence while she death-glares at her extremely uncomfortable-looking husband.
My coworker just turned around and walked away.
