We're checking out at the pet store, and the cashier has treats for the dogs. She puts out her left hand and says "Shake!" a few times. Girl dog just sits there with a funny look on her face. Cashier says "Aw, it's okay", and gives my dog a little condescending pat on the head and a cookie. Bitch.
I said, "You're doing it wrong. Your left hand is 'paw', your right hand is 'shake'".
My dog's not stupid you little twit, you were giving her one hand signal and a conflicting voice command.
