Shady Oysters

Customer: Oysters?

Me: No ma'am. I don't have any oysters.

Customer: What about any in the shell? I can just shuck them.

Me : Sorry. I don't have any oysters.

Customer : How does that happen? I mean it's not like the oyster has gone extinct.

Me: I've just sold out. They're very popular this time of year.

Customer: That's shady practices. You engage in shady practices!
