New Air chucks needed

So I stopped at KT to air up a tire that was low. I lost more air than went in. The Air chucks was so worn out it wouldn't get a good seal on the valve stem. After it went down to 4 psi I finally gave up and drove to another station down the street and filled the tire. I've had this issue at several KTs and the person that was airing up ahead of me was having the same issue. Change the Air chucks on the hoses please!
