The gas station air pumps are maintained by the same people who maintain the McDonald's ice cream machines 
It is the same issues where I am - air pumps either broken or not even offered. I have kept a portable 12v inflator in every car for years as that is the best and most dependable option...air when and where you need it. I also have not used a gas station air machine in years because they are loaded with water from lack of maintenance and I don't want all that water/condensation in my tires to corrode my wheels and hurt the TPMS sensors.
