gas roulette

When a car is used by more than one member of the family and the person who used the car and drained the gas tank last must pay to refill the tank.

While pumping gas, you try to release the pump trigger at the number you want it to land on in one try. The less risky people release a few cents underneath the target number then pump the trigger until it gets to the number. It is kind of reverse of russian roulette.

Going with a group of friends to a gas station (or convenience store) and purchasing each other 1 drink, 1 snack (usually chips), and 1 dessert discreetly. Then, you all come together as a group and try your snack combination and typically rate it out of 10.

The "game" of trying to decide if you should get gasoline today, or the next day without the prices dropping or raising in your favor.
