Iguana, that is the case with mine too. If a pax is large enough to need extension belt then common sense as you says tells us they are not fit to operate the exit...
Myself when flying, I inwardly cringe when an overly large perosn comes up the aisle, hoping they will not be blocking me in the aisle seat.... it's not because of them themselves, it's just the fact I don't fancy my chances if things hit the fan!!!
(Personally, I once climbed over a guy who was asleep because I couldn't get to the lav otherwise... with 3 hours to go holding it wasn't an option!!!) The guy didn't even wake up....!
Lol, I can just see that in "airline service posters that didn't quite make the cut" = Man with Butt out of window.....
