"Open 24 hours" joke

A woman walks into a 24 hour convenience store. She walks straight to the manager and asks, "Do you have any small notebooks?"

"Sorry," says the manager. "We're all out."

The woman shrugs, and asks, "Well, do you have any mechanical pencils?"

"Nope, don't have that either," says the manager.

The woman feels her stomach rumbling and asks, "Do you have Doritos? Nachos?"

The manager shrugs, "Sorry."

"Hmmph. How about Chapstick?" says the woman.

"Nope. Don't have that."

"My God!" the woman shouts, "If you don't have anything, you should close the stinking store!"

The manager shrugs, "Don't have the key."
