As somebody who flies a decent amount, seeing a fatty waddle to my aisle and stop is the worst thing about it. Their flab spilling over the arm rest for hours on end, their constant snacking because not eating is a concept they can’t comprehend…it’s just foul. Trying to see this thing fit into a seat is incomprehensible. It just doesn’t work, and as a paying customer, it is unacceptable to have to have this thing next to me trying.
