My goodness gracious! In order to be in contravention of 15 USC Chapter 1, I'd have to get together with every other endodontist in my area and make certain that we were all following these same charitable impulses. Sorry - this never happened.
I charged each patient (that would be "individual patient", not plural, not "customers") on the basis of the amount of work and time I projected I would have to perform in order to properly (and painlessly) complete the root canal work.
You make the unfortunate leap assuming that I "stole the cost of that procedure from another patient." If I "stole" any profit, I took it from the mouths of my family which I shall be more than happy to explain to those that guard the gates as the worms are feeding on my earthly remains.
