As others have commented, the machine at this location only dispensed half of the 5 gallons I paid for (sputtering at the end). The machine does not accept credit cards and I only had enough change to use the other fountain to get 2 more gallons (1 gallon at a time) and it only gave me half the gallon each time as well (Also sputtering). It isn't about the money as much as the inconvenience since I was camping in the area and had to find the location, drive to it to only get half the water I needed. I have used Primo machines many times and never had an issue. I would definitely not use Watermill again. read more
