This is NOT a good joke to tell a customer. Fuck you, asshole. Kindly die now, and let the rest of humanity advance.
ETA: First, just saw the post further down and I now figure this won't be greatly received. Second, context, it was said without irony in a conversation that was basically "My misogyny, let me show you it."
Though I would've thought without context, most people would recognize that jokes that trivialize sexism/domestic violence should only be said to people you know won't be offended. Standard social graces and all that.
