I edited my post to explain it more. Out here, people gamble about EVERYTHING. But the closest Casino's are a flight to Vegas (unless you're going to the illegal ones in Chinatown that sometimes get shot up...)
While at work, they would always do the dollar flip bet. Usually between like 5 people. It may take a while, but eventually it lands 4 and 1, making that 1 person the winner of all $5.
They also play a game called LCR. It's a dice game, where the dice says L(eft), C(enter), R(ight) or a dot, meaning you hold onto your chips. Everyone has two chips, and you roll the dice until one person wins, and wins the cash. It's a silly game, but it passes the time.
We also used to bet on what someone walking into a store would purchase.
