So, this is the pitch to , say, Tims "we want to generate a lot of revenue from non fares...so that means we want to charge you a lot of rent to open stores within train stations....many of which see large amounts of people for 2 hours a day and that is it, but there won't be parking for non train customers and it is not clear how many of the train customers will actually stop in the station to get coffee as opposed to one of the several coffee shops they pass on the way there.....oh, and by the way, to get in on this great opportunity you have to go the trouble and expense of accepting another form of payment....one that is inevitably linked to a credit or debit card that you already accept anyway!"
I think it would be more likely that Tims would respond with "nah, why don't you scrap Presto and just accept the Tim Card on the train"
