On becoming a Karen. Your thoughts and recommendations.

It’s finally happened! Had one of those frustrating customer service chats this afternoon where you know the rep is just following a terrible script from a terrible company. I stayed firm but made sure they knew it wasn’t personal—I can’t stand how companies mistreat customers and put their employees in impossible situations. But where’s the line between advocating for yourself and coming off like a Karen? I never want to take it out on the wrong person, but man, it’s hard not to get frustrated. Any advice?
