My kids had something similar happen when they were in high school. But instead of a gas station, it was a supermarket, and the driver put "The Wheels on the Bus" on loop on the PA

Working one job is hard enough. Imagine trying to be a bus driver and a zookeeper at the same time.

The driver was hit with a DUI but that was dropped. After reading a few articles it appears a fight broke out on the bus and the driver pulled into the gas station to deal with it, it got out of hand, had a slight mental break, and abandoned the little rat bastards on the bus.

I can't find out the demographics of the district but all it takes is 2 or more niggers to cause a problem.
