The Mother Of All Boundary Issues

(I work as a sales associate in a thrift store. One day I look over to see a customer walk into one of our fitting rooms and I suddenly remember that I have to tell her something. I walk over and open her door wide enough for me to stick my head in and talk to her. After I finish and close it back, I turn around to see my manager looking horrified. I stand there confused for a few seconds before I figure it out and quickly explain.)

Me: “Oh, no, it’s not what you think! She’s my mom!”

Manager: *looking relieved* “Oh, thank God… I was just about to have a long talk with you.”
