That's one thing you should not stress about... These places would have got $0 in revenue and $0 in profit as I did not know they existed without RN. As is, they receive in some cases $500 dollars in revenue per dine at about 80% of that going to them. If you assume that most restaurants sell product at 100% markup, I would say that they generated (500/2*.8) or $200 in profit for my dine.

If you are only using RN as your only form of marketing, then running a restaurant may not be your best bet.
