I heard that for years the only place in Vegas you didn't see slots was the restrooms...lol And I had also heard that the airport machines had the absolute worst payouts. Kind of the last gasp to remove the rest of the change from your pocket on your way out of the state.

But then things may have changed now, maybe they finally figured out that the guy telling all his friends "I had a great time while I was there AND I hit a jackpot while I was waiting for the flight home!" is great advertising.
