Overall, I'm really happy with the Menard's store in Marquette, MI. I agree with those who say that help is sometimes hard to locate, but when you can find them, they're helpful and friendly.
What I really dislike is the check-out system that they switched to a few years ago. The clerk now has her back to the customer, limiting eye-contact and social interaction. Where was the logic in that? A very poor corporate decision, if you are listening out there.
You have to bag your own stuff, too, which isn't bad when just a few items have been purchased, but is a nuisance when you are buying a large number of things, which is often the case in a hardware store. For that reason, I tend to limit the volume of my purchases there on busy days, and shop for the rest down the road at Wal-mart.
