Wrong. My argument is 100% valid all the time. People should pay for what they use. If they use 2 seats, they ought to pay for it, period.
Your argument is wrong 100% of the time. Using YOUR logic, if there's an empty seat on a plane, I should be able to fly free since "no one else is going to use it." That's the entire crux of the fat person's argument in this case.
Case closed.
Game. Set. Match.
I was thinking along the lines of leasing a small apartment and trying to fill it with furniture from a four bedroom house. Instead of renting storage facilities for the excess furniture, I would tear down the wall into the neighbor's apartment and put some furniture in there.
If they don't like it, they can move. :o)
