What's the best line you've ever used when someone does something incredibly stupid at the blackjack table that has cost you a lot of money? (I know, mistakes help us as much as they hurt us but that doesn't take the sting away from losing a very big hand).
The best I could do recently was "you're a fucking asshole." It felt good but I would have liked to be a little more creative. The guy didn't say a word back.
