Its not the actual thanks as such, we get a round robin via email, which is perfectly fine - I was interested in how well it had sold as I'd done a bigger batch than asked for as it wasn't worth my while doing what they wanted & it cost no more IYSWIM.
Also I heard there was some face pulling by some PTA members at a meeting as they just werent understanding the dish & I even had a couple of people not realise it was me making it, as started bitching & laughing to me about a disgusting sounding dish someone had offered to do. - A bigger batch had sold out in previous years & they had all eaten it & asked for recipes & it made a good profit & easier for certain diets etc, they just didn't know what was in it 
So I had thought of maybe offering as recipe cards to sell next time - but that was a different more open minded PTA, who have now mostly left, which is why I'd asked them to let me know how it had sold this time, as I wondered if the negative attitude would spread & affect sales,
the head of PTA seems okay, if a bit overly friendly on the run up to fetes etc & then far less so at other times, but I've found the others not so much so, very different to the lovely crowd we had before, very gushing when they want something, dont even notice you otherwise & damn right rude & gang up if you disagree with anything they say or do & using boardroom speak in meetings & emails which I personally find OTT, very clique too, which I suppose is what puts me off more as I find it very pretentious.
I know its for the school, but feeling more like giving my time in other ways TBH, as I'm less enamoured with them as time goes on -
but I wasn't sure if wanting to know if my offering had sold well or not was a big ask - it was the sort of feedback we always got with the last PTA leaders
- maybe they were just particularly good at handling volunteers
