The guy I talked to lie to me. My husband needed nitrogen for his tires. I called ahead and asked how much it'll cost. The guy asked "does it have a nitrogen in it now?" I said yes. He said "just come in, we will do it for free". When my husband came another guy that was in the register was rude, not noticing him needed help until 20 min or so, and said they will charged $10 for each tire. WTH. Not a good way to do business.
