I watched the video for curiosity's sake. Both Cam and the other passenger were sitting in the same area. Not first class.
The other passenger just had the front seat behind the wall, which always has extra leg room.
So, they likely paid a similar amount for their seats. The other passenger probably would have profited. But, money isn't everything.
Looks like there are other seats in that row, too. Did everyone turn down Cam? Why would he only ask one guy?
Back of the bus comment was really dumb. ?
