Free Air Costs Nickel Unless— (Jan, 1933)
Free Air Costs Nickel Unless—
ANEW device recently patented makes it necessary that motorists either make a purchase at a filling station or pay a nickel for the shot of air they put in their tires. In operation when a coin is put into the slot it releases enough air to inflate five tires. A special lever returns the coin.





The gas station near my home has an air hose that only functions after depositing fifty cents into its coin slot. By my calculations that’s a 1000% increase over 75 years. That sounds like a lot. On the other hand, it works out to only six tenths of a cent a year. That sounds like a good deal. Given that most stations don’t charge at all, it costs an infinite percent more in 1933 or 2008. That can only mean a zero percent yearly increase. Given inflation over the same period does that mean the cost has actually gone down? Hmmm….
