When I worked in retail, I saw way too many near or actual fist fights break out from when people said off the cuff, passive aggressive comments like that to the wrong person on the wrong day and either it escalated or someone just snapped. I mean, adults ending up bleeding and the cops being called and two people being driven off the lot in cuffs.
It's not worth it to me to end up in jail or the hospital just because I wanted to get in the last word or "prove" to someone that they're in the wrong and I'm in the right.
