Boomer furious about volunteers being hydrayed

Im running a group of volunteers who are working outside all this week. Unsurprisingly, manual labor in summer means everyone has been ducking into the kitchen to refill their water bottles .

We had one older volunteer for the week, and doing him a kindness set him up with an indoor job with a fan to keep him more comfortable.

He apparently thought this meant he had some sort of supervisory role and started ordering people around. We talked to him a few times. Yesterday, he hung up a sign forbidding anyone from refilling their water bottles, and locked the kitchen door.

Thankfully I found this quickly, and he started huffing and lecturing as I took the sign down. According to him: the water was costing the city "a fortune", people relying on it was making them weak and lazy, no one needed that much water, and people drinking it was what was causing all the volunteers to be so fat.

I decided to reorganize things this morningand his indoor, seated and cooled position went away. We still had him in a seated task, but he had the full force of heat and sun.

He quit three hours in. To his credit, I dont think he drank any water the whole time...but he should have.
