An old colleague of mine from here once told me of his plan to return to Vegas and get rich. He was going to install slot-machine public toilets on the Strip. You'd have to put a coin in the slot and pull the lever to get into the toilet. And if the reels were not your friend? The door would stay locked. He envisioned great long lines of people dying for a piss and throwing handfuls of metal into the machine for the chance of taking a leak before their bladders exploded.
He works in advertising now.
