A woman walks into a grocery store

So a woman walks into a grocery store. On her grocery list of items is milk, eggs, bread, and beef.

She walks to the dairy section and grabs some milk.

She then walks a little farther down the aisle and grabs some large brown eggs.

Then she goes to the deli and picks up a lb. of ground beef.

Finally on her way to the cashier she picks up bread in the bread aisle.

She reaches the cashier and scans the milk, eggs, bread and beef and the cashier says "You know, I bet you're single"

The woman, shocked, says "Why, yes I am single. How did you know that."

And then the cashier says "because you're ugly."
