If you need air pressure check don't go to The Colony off 121 or Cross Roads Locations. I waited over 15 min for anyone to come to check my air pressure at the Cross Roads location, and at The colony off 121 location, I waited 20 min. I finally inflated my own tires with your machine and when I was filling the last tire in the Colony, some blonde hair kid came out to tell me it was illegal for me to fill my own tires. I asked him how long a person needed to wait to get an air pressure check, because I had been waiting 20 min. He said we've been busy. The people at Cross Roads never came to check in 15 min, so I left and went home. What ***
