Free Air?

Needed air for the left front tire on the rental car. We were in a truck stop/convenience store thing and looked all over for the air. Finally found it behind a parked 18-wheeler. Went around to the other side and when I picked up the hose it was just whooshing away. There was a split in the hose near the chuck. Across the street we went to the next gas-n-go place. They had one on the side that you had to put money in to get air out. It said 50 cents, but after I dropped the first quarter in the compressor kicked on, so I tired to pump up the tire. The pressure coming out of the hose was weaker than if I was exhaling through a straw. The sign said 50 cents, so maybe you had to put both quarters in to make it work right. I put the second quarter in and it didn’t get any better. On to station #3. Their air was also 50 cents. More pressure, but not much more. At least I got the tire pumped up before the time ran out. Of course I have no idea what the tire pressure was because the gage thing attached to the chuck was broke. I just made the side wall look like the one on the other side of the car.
