Obviously Not A People Person

(We have booths at which we can only seat groups of three or more. There is a couple with their young child sitting in one. A couple comes in and I go to seat them.)

Me: “Hi, are you here to eat, or are you just having some drinks?”

Customer: “Eating. Can we take a booth?”

Me: “Sorry, but we need to save them for groups of three or more.”

Customer: “What about them?” *motions at the couple with their child*

Me: “They have three people sitting there.”

Customer: “What? Babies aren’t people!”
