I'm old enough to remember some things that you younger whippersnappers probably don't. For example, I remember a time when gas stations had air for filling tires for free. Yes, FREE. You just drove up to the pump, and at one end of the pump island there was a hose on a retractable reel that you pulled out, brought it around to each of your tires, and filled them. For FREE. Nowadays, though, you have to drive over to a dispenser that for a dollar gives you just enough time to fill three of your tires. Well, that's inflation for you.
