He drives a bus, basically transporting people from one city to the next. Going from point A to point B.
Someone, somewhere, made a complaint. One, lone complaint, and they call up today and fire him.
Not to mention that the complaint is baseless, since my dad would remember nearly hitting a truck on a bridge. Oh, and the bridge? No way a truck and bus could both fit on this bridge, it's too small.
But the place of employment doesn't seem to care, since someone complained.
