One time, when I was at six flags, I witnessed something super sad. Infront of me was a Fat black guy and his cute kid. The kid wasn't really old, but I'm not good at guessing ages. The kid looked like he was JUST barely tall enough to go on the ride, so this was probably his first time and he was probably super excited. Anyways, I see the guy trying to put on the overhead thingy that secures you and he totally can't do it. He can buckle it but not actually bring it low enough so that it "clicks" and is actually secure, if that makes sense.  He tries to adjust. Probably tries to suck in his gut but you can't really tell when someone that fat tries to suck in their gut. One of the teenagers who do seat checks tells him he can't go on. At least the guy didn't make a scene.  Anyways, I don't remember if the ride was one of those that allowed children that were slightly shorter to go on if they had a parent, but not if they were alone, or if the kid/parent didn't want the kid to go alone by himself, but the kid left with him, looking slightly deflated.  They spent a long time in the line, and there was one of those trial seats before the line started, where you can check if you'll fit. Idk why he didn't use it, but he didn't. I felt super bad for the kid, he wasn't fat at all. I actually really wanted to tell the parent that the kid could go on with me and my friend and wait at the end of the line for him, if that was allowed. But I didn't because 1. I'm a guy and I feel like society views guys as creepy if they tried to do this. It'd probably go over better with a woman. And 2. I just didn't think it was socially acceptable. I never saw the pair again throughout the day, but I hope the kid had some fun.
