My lads school is in a bit of a Channel4 shockumentary type area. Not unusual to see parents dropping off at 9am with a can of Special Brew on the go. (In PJ’s / all-in-one suits obviously). Anyhow, they had a Pimms tent at last years summer fayre. The duffers serving had the Lemonade to Pimms ratio the wrong way round, so they ran out of Pimms somewhat early & ended up trying to sell just lemonade. The aforementioned clientele were not too impressed with this. I feigned indifference & pressed ahead with the Tombola regardless.
I say good on the OP’s school.
It’s this year’s fayre on Thursday, & they are actually selling Beer this year. I’m in attendance, on the Tombola again. I’d offered to give laps of the feild on the back of the cargo-bike but the Headmaster said no.
