There was a poster warning campus students of deviating from normal behavior especially when on campus buses. The message said that disruptive behavior is disrespectful to the driver and other passengers and actually delays bus service.
There was also a drawing of a person on all fours eating something from the floor of the bus. Apparently someone thought that the message was not good enough and had to add a few words of their own.
The added words read ‘friends don’t let friend suck hot dogs off the bus floor” given the picture on the poster, that was the most correct message.
