I'm from a medium-sized city on the US midwest, so my experience is that bus drivers sometimes decide "Fuck it, I'm not coming today," on a route where the schedule says they should be there every 30 minutes. I think most Americans outside of large cities have a similar experience. I was really struck going on vacation to San Francisco how together the bus schedule was, compared to how "meh" laid-back the city institutions I interacted with were about everything else.
Granted, I was trying to go up Grant in Chinatown, but you clearly haven't tried a crosstown bus in Cincinnati. Scooby Doo would have an easier time making a cake.
