I forgot to math and oopsied a 3. Here is an example breakdown of prime costs for a restaurant. Prime cost doesn't include non variable overhead like rent, insurance, and utilities.[1]I don't think my lack of math skills takes away from my argument that if Apple Pay can reduce payment transaction fees to 1% of the charge, it will have a major increase in net profits for small and medium restaurateurs.
