jookbeard - This guy is the coach. He's been more successful as a player rather than a coach though. https://en.wikipedia.org/wiki/Ioan_Sab%C4%83u
Incognito - This was a 1 day assembly. Here in Romania, I don't remember ever being a food service offered by the organizers of the assembly. However, just outside the gates of the assembly hall, and this is pretty much valid everywhere, there are vendors that come with their trailers, vans and tents and make their own serving areas. Sort of like open air restaurants. There are usually several of these vendors, which I believe are somehow pre-approved in presence by the JW organizers, and offer a wide variety of foods,drinks, snacks and all kinds of stuff. At larger conventions you can even find kid's toys, souvenirs, almost like you'd find at a street fair.
It's not unusual for cab drivers to hang around the area too as the assembly hall is on the outskirts of town and they use the opportunity to get lots of clients.
Anony Mous - Haha! No wonder they never invited you again. So, that's 10K per assembly day. With the immense size of the US and its JW population (relative to other countries), and factoring in that some areas could have wealthier JWs, they must be raking in a ton of money.
