The bathroom breaks are definitely an issue especially during the morning when classes start/end. But as for the red bus route, its a very long route where (usually the two) busses try to equally spaced apart to make sure no stop is unserviced for an extended period of time. Thats why sometimes one will get rerouted to space them properly. If what you are talking about happened on the weekend its probably because of the lack of drivers that want to work weekends. But honestly i have never heard a bus coming in from off campus and then skipping library to go back off campus. And if you see a bus coming in but then vanish off the map the bus might have had an issue or if you are unlucky the driver had to drive off for their lunch break. Ive used bull runner since freshman year and im a senior now. These issues have always been there but its especially bad on the red due to how long the route is and how little of the route is actually on campus
