The gas station by my house stopped having free air

The gas station by my house can do this. I’ve asked and had it done for me. It used to be free, but then they changed it to 50¢ with a sign that said “Please ask inside for free air” so I went inside and asked and they flipped a switch and the machine turned on for a few minutes.

And we had our free air then
Tires were tires and men were men
Mister we could use a blast of no-cost O2 again

It costs money now because they have to use cool air. They used to use hot air, but it’s all being used in Washington now.
