As a former comic book store manager, stories like this always make me cringe. If I found out an employee of mine talked to any customer in this way they would be fired immediately. I very much hope that guy is gone the next time you check the place out because a good local comic shop is a wonderful thing and the friends you can meet there can last a lifetime. Good luck, and I’m sorry you had to go through that at all!
I’m sorry that happened to you and others @MegRojahn
