Several years ago, while Michelle and I were traveling through Texas, we stopped at a restaurant that was at the base of a very large cross. I don't remember where it was but it wasn't in a city, and there was no indication that it was different than any other restaurant. Given the large cross that appeared to be on the same property, we assumed it was owned by a Christian. Inside, it had the appearance of what I would consider to be perhaps a mid-class restaurant. There were a lot of choices on the menu, but no prices. The business model was that you could pay what you thought it was worth, or could afford. The owner told us that he generally earned probably more than if he had priced the menu, but that people did occasionally pay nothing, or next to nothing. Looking online, I can see that several people have tried this through the years. One highly publicized vegan restaurant in Sydney, Australia closed after collecting an average of $3 per meal from customers. I don't know if this restaurant is still in business or still following the pay-what-you-like model, but I am thinking that it was working for him because it wasn't in a city. As people would have to drive there, he didn't get a large homeless clientele or the kind of people who were just looking to get something for nothing. Plus, unless you were familiar with it, you wouldn't know that it was that kind of restaurant until you looked at the menu, so travelers who stopped came in expecting to pay for a meal. Given today's climate, I wouldn't doubt there would be an organized effort to bankrupt them by people who hated the Christian message.
I personally would try the food, then evaluate whether the provider(s) were sincere, based on it's quality. I'd pay what I thought it to be worth competitively. Then sit back hoping to not get sick in the next 8 hours. Frank
I know of a fishing guide service which takes payments this way they do well all but the extreme religious views he speaks of to most customers.
