If a person can not fit into a seat, and that requires him to lift the bar and sit......he has then taken someone else's seat. Where should the other person sit now.....since the 'over weight gentleman' took his seat??? Come on ........if you need two seats, you should buy 2 seats (maybe second one with a discount but you definatley should buy the space you need, instead of LITERALLY stealing someones else's space. This seems like such a no brainer. Either you fit, or you dont.
