Mere minutes after rejecting a Home Depot employees offer of assistance with a curt shake of his head and the phrase No thanks, local man Garrett Hoffman, 44, reportedly came crawling back for help Monday. Excuse me, Im looking for foam sealant, said Hoffman, returning with his tail between his legs to the very same salesman he had just moments earlier arrogantly brushed aside as he strode with unfounded confidence down the plumbing aisle. I looked next to the fiberglass insulation but didnt see it there, and it wasnt by the other spray products, either. Maybe its in the back? At press time, the once cocksure customer was barely able to raise his head to look the floor salesman in the eye as he returned a second time to meekly request help getting the sanded plywood down from the top shelf.
