Not really
Even before his sacking the main news was Fat Man eats pie on bench and played up to the Non League Stereotype, which is a shame because its very much not the case anymore. Hard enough to get those Prem Lge fans down a NL game as it is without Shaw playing the fat non league player card, people will laugh and say "ahhh good old non league" and not bother forget Deacons performance and remember the Fat Keeper who does not even play anymore.
Also If you prearrange such a thing with the protagonist it would not be a bet, its fraud, Sutton regardless of level should protect their integrity
if you offer a novelty bet like that then the person at the center of it is going to find out about it and once he has anything that happens thereafter will be influenced by the bet being available - whether he ate the pie or not. i don't have a problem with novelty bets and if they are going to be offered then you cant really come down hard on people who they revolve around, imo
i think the whole thing is an over reaction, including the idea that a bit of fun gives off a bad image of non league football.
