Never is, I suppose, that whole TANSTAAFL thing. On the other hand, last night, on the way back from work, I started to get that shifting feeling in the tail, the back of the exploder yawing around more than I like, and I knew the right rear was low on air. So, a couple bucks in my pocket, I swing into the Lincoln Oasis, and pull up to the air pump.

And discover it’s free. Free? Free air? I know some stations hae an inside button that allows the attendant to turn on the stuff, but here was an air station, at a gas station that charges 30 cents more per gallon than the norm, without any coin slot, just a pushbutton.

So I filled the tires and drove on. You take what you can get when you can get it.
