Customer: Last year we bought 43 hams from you. I'd like to do that again.
Me: when did you want to pick them up?
Customer: Right now.
Me: Um.... did you place an order?
Me: I have like 6 hams in the entire store.
Customer: What? !?! How is that possible? !
Me: We're almost sold out this year.
Customer: Well what the hell am I supposed to give my employees? I'm going to look like an asshole. Thanks a lot!
