All these people keep debating over whether or not an adult with a surgery that makes it impossible for them to eat more than a handful (unless they stretch their stomach out over a period of years causing potential death) should get to pay the child's price while at a buffet.
They don't choose to eat less, they must. I'm very sorry, but this is not up for debate. If you say that they choose to eat less, then you are so horribly wrong that it's just sick and a little research before you talk wouldn't hurt anyone involved.
Comparing it to getting a young child in to the parks for free? Well, they really are over the "free" limit. No surgery made them grow up. Surgery to help you from death is slightly different than aging a year, and maybe it should be viewed as such.
Lastly, I applaud the people that WANT to pay the child's price. You see, knowing how little these people eat, there is nothing stopping them from eating that aforementioned handful and then complaining that they feel nausea (because half the time, many people do feel sick after meals so there's no lie there). Then they could get it for free! Like ANY other adult that ate that much. So if everyone wants to talk about how shameful it is that they get a discount for physically not being able to eat more than a small child no matter how much they really want to, just remember that they don't have to pay at all if they really were scamming. They're just trying to make things fair.
