I would guess, and it is only a guess, they are on a fixed contract with targets. So club buys x number of pies from piglets and Seduxo or whatever their name is are paid to sell said pies but with a target of not to cook too many as uncooked ones can be saved for the next match. Probably some...
Possibly but the ones in WSU seemed to know what they were doing just didn't seem that happy to be there ! The guy that served us took half his serving time just taking the two bottle tops off ..... hmmmmm.
