The Boston Business Journal reports the T has some space in several stations (Back Bay, Forest Hills, Harvard, Alewife, North Station, South Station, Airport and Malden Center) it's looking to rent for retail use.
The Journal notes there are several prohibited uses, including the sale of tobacco, scratch tickets and popcorn.
Popcorn? T spokesman Joe Pesaturo says the T has had enough with popcorn because it attracts pigeons and "too much of it ends up on seats and floors of subway cars."
Ed. note: Dunkin' Donuts HAS to rent one of the Back Bay spaces - the walk between the two current Dunkin' stands is really just too long.
