A Drill Bit Confused

A very p***ed off customer comes to me and angrily shouts from the get-go:

Customer: “The drill I bought for my husband doesn’t work! It doesn’t rotate!”

Me: “I’m sorry to hear that, ma’am. Did you bring it with you?”

She casually tosses it on the counter.

Me: “I can see why your husband was having issues, ma’am, but this isn’t defective.”

Customer: “How do you know?! You haven’t even touched it!”

Me: “Because, ma’am, this is a $2 screwdriver.”
