The Feasibility of Coffee Delivery

While i'd love coffee on demand, it seems like the margins are so low. Already I feel ripped off paying $3 / cup. Add another $3 delivery charge and I'm really getting gouged.

With everything on demand, I wonder if even the most succesful will ever come close to profitability. I use Favor frequently, which costs $5 per delivery no matter what. There's no way they're making much money on this if it takes a courier 30 minutes to get my order. I hope I'm wrong but just my 2 cents.
