Air on Credit

Just noticed this for the first time today. Oh, gas stations have been charging customers for air, for a long time, but we see the results of inflation, when it comes to inflating your tires. The cost is $1.00 and now you can use a charge card! I wonder how many tires you can inflate for $1.00… To think, we used to ride our bikes to the gas station and fill our tires for free and then buy a candy bar for a nickel!
