Update! Environmental Health sent me an email that they were not impressed, inspected them, and are now "working with the business to ensure adequate safe water is available on site."
Make the good trouble.
Apologies for not reworking this to fit Bluesky posts, but here's a local fight I'm having with High Lodge Farm and their moderately expensive "we have straw bales in a field for your kids to climb on" regular school holidays event.
I've been copying Environmental Health into all of this, btw.
