Maybe it’s me. Where I come from I can’t get help. Maybe it looks like I’m not approachable, Maybe it’s because I am old, fat and ugly. Maybe I’m invisible. But I can be standing in an aisle at Home Depot, Lowe’s, Walmart or any other place of business that is willing to take my money looking for something and have a store clerk pass by me without acknowledging me or asking if they could be of assistance. - Billy
