also, If it is just some random Karen butthurt and not an employee, I literally just ignore them. that shit gets on their nerves so much. Just pretend they are not even there. Don't respond, don't look stressed, don't stop what you are doing, just act as if you can't hear or see them. don't even look at them. It really makes their blood boil. they are looking for a confrontation where they can look righteous, don't give it to them. If you engage, you look like the bad guy and the mob will turn on you. If you treat them like a ghost, and not even look at them, their blood starts to boil and to anyone looking, they look like the bad guy. It is a pretty great thing to witness.
