True story that just happened today.
I was in Fairview Mall after picking up my pool cue that had been re-tipped at F G Bradley games store.
I went down to the food court for dinner, and while walking through it, I felt a tap on my shoulder. I turned to see a group of 4 late teen girls, one of whom said "I love the colour of your hair." I answered with a smile "I wish it was black again", as it is pure white, and even though I'm 79 I still have pretty much a full head of hair. And we all immediately kept on going our own ways.
Many sex workers have said the same to me, but never a civilian "out of the blue".
I would never consider trying to pick up a woman of any age in a mall, grocery store, or any other public shopping environment in this day and age. First cuz my chances of succeeding are extremely low, and the chances of being looked at as a creep are much more likely.
These days I wouldn't even try it if I was 26 again.
