Yeah, that's the ticket!

I was playing today at Caesars Palace. During one hand, a player put out six red chips ($30), in two stacks of three chips each. For some reason, the dealer saw only one of them (probably because the second one was kind of close to the pot, and he thought it was already part of the pot). He announced the bet as $15. I asked him to check that. He looked again, realized his error, and said, "Make that $30."

A few seconds later he quipped, "I'm just so used to those two-and-and-half-dollar chips."
