A nice metaphor from my friend

I wrote an e-mail to my friend regarding what happened at the Casino, and this is the metaphor she wrote (this is the same friend who wrote The Cafe Toscanini in Fremolia): "Sounds like typical casino behavior, though, what with the cheating and the chiseling. You should never trust a casino to be fair to you, that's like trusting a dog with your steak dinner."

I like this metaphor. I think it's clever and funny. Good job!
