The Only Number This Is Good For Is Number Two

I’m a female employee at a hardware store. A male customer walks over to me.

Me: “How can I help you, sir?”

Customer: *Grabs a toilet seat off the shelf.* “I want to… uh… buy this.”

I take him to checkout, ring him up, and hand him the bag.

Customer: “So… can I get your number?” 

Me: “No.”

He freezes for a moment, then sets the bag back on the counter.

Customer: “Well, then I want a refund on the toilet seat.” 

Me: “Uh… why?”

Customer: Dead serious. “I only came in so I could get your number.”
