I was playing a slot machine in a Vegas casino. It was my first time
in a casino, and I wasn't sure how the machines operated.

"Excuse me." I said to a casino employee. "How does this work?"

The worker showed me how to insert a bill, hit the spin button,
and operate the release handle. "And where does the money come out?"
I asked. He smiled and pointing to a far wall said,"Usually at the ATM." --Reader's Digest
