For years I've been driving past Jenkin's True-Value to go to Tomchek Ace Hardware. The old man or his son are almost always there and provide good advice. The rest of the staff are hit or miss depending on who you ask and what you're asking for. It takes a lot of experience to be knowledgeable on everything a store like that sells. If you want to know WHERE something is, ask anyone. If you want advice on a tough problem, find the old man or his son. (Jenkin's staffed with kids and now they're out of business.) I've never had a problem with a return either. I bought the wrong style air chuck and returned it opened and got the right one plus the difference in price back.
