In all fairness it's kind of as expensive as you want. I often end up at Starbucks and buy a grande coffee for $1.85. Sit down at a table and grab a dongle for my phone and use the wireless charging as I use the provided internet for a while. When I'm ready to head out I get a full refill for free and hit the road. That's two large coffees for about 95 cents a cup and the use of their services.
