Mommy and Daddy Pottery Barn

Is it wrong for me to be disturbed by the fact that my PB store manager and our district manager have nicknames? And that those nicknames are Daddy and Mommy, respectively? I've meant to rant about this in a while - my second week at work I overheard a manager telling another manager "Daddy was on line 1 and wanted to talk to him". Later that day, there were rumors that "Mommy" was coming to visit next Wednesday so everybody needed to dress up.

Is this a retail thing? A PB thing? A when-your-manager-is-gay-everything-makes-sense thing? I can't imagine district manager Diane knows her nickname is Mommy, or does she?
