Even if they do have to pay for it, you do realize they are making an enormous profit? I used to work in a distribution center that housed all the products for restaurants on a university campus. So everything food related came through us. Soda syrup comes in 5 gal. bags in a box (BIB) and a Coca-Cola Classic BIB can cost around $30 (That's what our university's contract with Coke set the cost as it could be different every where). A case of 20oz cups (the standard Large size) averages about $25 (or less even). And there's 500 cups in that case. That 5 gal. of syrup goes a long way. They can use more than one case of cups per case of syrup. But for simple math lets just say one of each. They pay $55 and serve 500 people at $2.50 (I like round numbers). That is $1,250. Nearly 23 times what they spent. If my math is correct that's 2272% profit. My math may be off, it never was my best subject (I move boxes for a living...) but regardless, my point still stands that it doesn't matter if they get it for free or have to pay for it, their profit margin is outlandish. A few more free refill places wouldn't hurt them much.
