I believe the manager would not come over. Reason I have experienced the same thing in Home Depot. The managers hide off the floor and refuse to come out. I was a store manager for years and I cannot imagine ever refusing to speak with a customer that had requested to speak with me.

I even suspected that perhaps this had been some type of directional training from Home Depot. A good friend of mine in NYC related a very similar story with a manager refusing to speak with him at his neighborhood store.
