How TTC can be benefited from the Subway stations

In Toronto, at the subway stations, many people pass from one place to another every hour. They are of different ages, genders, and different economic conditions. We can build small shops beside the long platform. That will bring money to TTC, and people will be happy, especially women, to buy their necessary staff and groceries and eat good food while watching platform trains moving. More people will be interested in taking the Subway for transit. It will be good for security too, as there will always be some salesman at the station. We will have a well-maintained washroom at every station.
