Did you say to the manager who was closing that you wanted the GM to close because you like them better or prefer to work with them for some other reason? Yes, that was hurtful to a person to be told they were not wanted and not liked as much as the other person. That’s why it was rude.

Also, the manager does the managing, not you, the employee. It really wasn’t your place to say what you preferred.

I’m glad you understand what you did wrong.
