I got on a bus once without the bus driver knowing. It was a free shuttle ride so it wasn’t anything mischievous. But when he saw me, he was surprised because he thought I have missed my stop (he didn’t want me to loop around again). I cleared it up with him. He smiled and then told me of a time a passenger actually looped around the bus circuit a few times:
"I remember driving this guy and his 5 year old son once. They both got on just around here but they didn’t get off anywhere. Just stayed on the bus for the entire loop. I thought he was loss or something so I asked him, where he was going. He said, market. I said, we already passed it. He said, oh I know. I just wanted to stay on the bus a little longer so my kid can sleep. He sleeps better on bus rides."
