200kjoules of heat must be removed from a gallon of water to cool from 55F to 32F (out of the ground down to pleasant drinking temperature).

Assuming a COP of 2 for your compressor (conservative), that's 100kjoules or 1/36 of a kWh.

High price for a kWh of electricity is $0.25 in the US. So for your $2 subscription, you can pay for 8kWh per month or enough to cool 288 gallons of water or roughly 9 gallons per day. More than anybody would rightly use.

What a fucking ripoff.

Not to mention that, in a place like a public park, 55F water is totally fine. It isn't the coolest most refreshing drink of all time but it's damn good from a public fountain on a 90F day.
