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!
