Marcus, at Whole Foods and Trader Joe's, you are a chick magnet (if they're 70 and buying oatmeal or bananas, or wondering whether you're Ellen DeGeneres' DJ).
They are alarmingly nice to you. Age strips away lots of B.S. and crappiness. So when you tossed "Oh, it's not a good banana day" at that 30-ish banana buyer and walked away from her, that was a good move. She'll be way into you in 40 years.
