the way i look at it ..if you are so big that it takes 2 seats to fit you ,you need to pay for both of the seats..i dont know if it seems cold ,but it just bothers me how when people get that big all of the sudden people treat it like it is some sort of irreversable disability ,and they need all sorts of special accomodations.. i have never been that big, but i got up to 220 at my largest and it got to the point where i was sick of being fat so i got up moved more and ate less.. it just takes willpower and in some cases it takes a little shove to get started..if having to pay double to travel isnt a motivator i dont know what is.
it isnt cruel,what is cruel in my opinion is pampering people that unhealthily large.(im not sure unhealthily is a word but i think you get my drift)
