Ann: Largest Pizza Hut Franchisee in Canada Converts to Full Algo, page-7

There may be a trial before you buy type arrangement in place where there has been a year of free or very low fee use (and probably no install fees) and after that the fees ramp up to normal. That would benefit dts who get the tech into stores to expand footprint and get customers dependent on tech, and can later point to benefits of tech experienced by those initial customers (who contributed little revenue initially so dts could fine tune tech in practice and get up and running in an operational sense) and charge full new customers full fees/installs etc from the outset (through a sales team). That would all be commercial in confidence though and company and initial customers wouldn't be able to talk about it. Which might explain why there is to date little revenue flowing through and nothing being said about it. But that is all just a guess and IMO.
