Mixed Up Mincemeat

I work in the meat department at a supermarket. A lady comes up to me.

Customer: “Your mincemeat is advertised cheaper in the catalogue!”

Me: “No, ma’am, we are selling it at regular price.”

Customer: “No! You’re not honoring the advertised price!”

She leaves, drives home, and returns with the catalogue! She holds it up to my face.

Customer: “See?! It’s supposed to be on sale!”

I flip to the front of the catalogue.

Me: “This is for [Other Supermarket].”

Customer: “…”

Me: “…”

Customer: “Do you have directions?”

Me: “Certainly!”
