I think the ones I saw recently were all members of the cult. They're overly religious and their family and children are often working there, children hate it and the cult. They try to keep costs low, donations from their work high, and it seems to function efficiently with a religious fevor. I've never seen much excess use of money from sushi restaurants. Haven't been to a chick fil a in a while but maybe like that culture but less friendly, all family and they're thinking of more efficient ways to donate. Many sell merchandise and try to sell lots of high profit goods. I'm sorry if this isn't a good answer.
Edit: I forgot about a sandwich shop (the yellow deli) I've heard that is always open that is a cult. I never been but it sounds a lot closer to this cult except they seen to recruit more and focus on cute receptionists girls working at the counters.
