PSA: Isn’t air free?

Does your car tire need air? Turns out most places (not every place, as I have now learned) will flip the switch at the air pump to give you free air for your tires. Some places like Wawa and Costco will just have it there for you. While at other places, you might need to go inside and ask the clerk to turn it on for you. It doesn't hurt to ask, but also it maybe a good idea to keep a cheap tire inflator in your car for times like this. You have options! But also, free options lol
