Deserve has nothing to do with it. Avoidable and unnecessary, 100%. All the way around, for all involved. But when a belligerent Karen with children in tow can't think better but to lean into a verbal confrontation with a stranger, don't be shocked when there are consequences. And don't be so Pollyanna. Most of us live in the real world. You too will get your mouth slapped if you act the fool to the wrong person. Check yourself before you wreck yourself, noodle. Words to live by. Now go to bed.
