It is usually one seat in a center row of a coaster but yeah, most rides have a special fatass seat or car. I have watched as a whole ride has to be shut down while 3 employees have to try and push down on a bar or harness to try and lock it because the ham doesn't fit. It is disgusting to watch them try and wiggle the fat rolls around to into the seat like jello filling in all open areas. I love going to theme parks, but the amount of disgusting fatasses riding around in motorized scooters is getting worse every year. At Disney, they call themselves "Pooh Sized" like it is cute or something. And it isn't just one, usually it is a whole family, all fat 2 or 3 on scooters riding around like they don't care about anyone else.
