I once was in a Home Depot looking around and checking out their lumber when some employee comes up and asks me if I need help. I tell him no, I'm just looking around. The dude got this strange look on his face like I just told him that I want to sleep with his daughter or something. He starts following me all around the store all the while making it quite obvious that I'm being watched.

Grade a jerk. My only regret is leaving the store without going and complaining to the management. I wonder how many others he drove out of the store by doing that.
