​Would a store that only sells a ton of soft drinks ever work?

Edit: I meant fountain drinks!

Was talking about this with my girlfriend the other day, about how it might be a viable idea to open a store that only sells soft drinks, and carries as many types as we could get our hands on.

From what I understand, the profit margins are pretty high, selling only soft drinks wouldn’t require a ton of employees, or a ton of training, it would mostly be a matter of getting the soft drink companies to agree to let us sell their syrups.

Any idea if this business model has been tried before, and if so, is it something that could potentially be viable? People could come in and get just about any soft drink they could think of, and we could even have a subscriptions for people that want to come often, like Panera’s Sip Club.
