I am wondering if that will be question for much longer. Today I was driving home and decided to check my tire pressure so I pulled into the closet service station and found the air hose. Just as I was about to get out of my vehicle I saw a sign and a coin slot for $1. It took me a few seconds to realize I was supposed to pay for the air. I thought you have got to be kidding and headed up to the next station only to discover the same thing. I have never seen this before that I can remember but figured it cannot be everywhere and I headed up the road to the next station where I found it was only 50¢, what a bargain. So not only are we gouged when we buy gas we also now have to pay to get air. What is next, paying to use the squeegee or having to pay to dip the squeegee in water?
