The school my child goes to has a fabulous summer fair, and much respect to the PTA who organise it each year. In the run up to it we get asked to donate a bottle for mufti one week, chocolate for mufti another, soft toy for mufti another (the mental load associated with this could be a whole other thread...)
This year there is a new request: money in an envelope for mufti, minimum 50p. The envelopes will then be used for a stall where you pay 50p to buy an envelope, not knowing what is inside, with the idea you might win more than 50p.
Another mum on the (notorious) WhatsApp group tried to clarify this as they didn't understand how this worked as a school fundraiser, as if you all put 50p into the envelopes and the summer fair charges 50p for each, the school makes 50p for each 50p donated. If you put £50 into your envelope, the school makes 50p for the £50 donated, so essentially £49.50 of your money is a donation to another parent instead of the school. It has been clarified that this is indeed how it works, but the hope is the person who won more would spend their winnings on other summer fair stalls.
AIBU in thinking this is batshit? Some parents who had initially thought the money in envelopes were for donations to the school rather than a crazy stall where you are guaranteed to get at least as much money as you paid back are somewhat cross as they would not have donated money to such a ridiculous scheme.
(for the avoidance of doubt, there are no empty envelopes as apparently else this would fall foul of gambling rules, so it is literally a stall to get the same amount of hard cash or more for the money you pay. My mind is boggling.)
