How easy it is to pick out flaws when one comes from a negative point of view. I'm betting someone with a positive point of view might well have found just as many good things to praise the same driver for. FYI, it is the driver's responsibility to walk to the back of the bus and check everything out at the end of the line before allowing passengers to enter the bus.
Just because a passenger is having a bad day doesn't mean they should complain about everything they can think of. On the other hand, just because a driver is having a bad day, there's no need to take it out on passengers. GROW the F*** UP ! You each have the ability to CHOOSE to be happy and demonstrate the manners your Mommy taught you !
