Hmm, the place I buy my groceries I have shopped at for almost a quarter century. I know everybody there, and they all know me. None would be so forward as to comment on my purchases, and any conversation centers on the weather, or other mindless blather. I usually try to joke around with the cashiers, but the teens and twenty-something girls act like I am hitting on them. Girls under 30? Eww, I prefer to flirt with mature women, not kids.
At other shopping places, no one comments on what I buy because I have the sort of face that if I am not smiling, I look like I just might reach across the belt, grab you by your ears, rip your head off, and skull fuck your decapitated head amid my groceries while your body collapses to the tile in a bleeding convulsing heap.
Not that I would ever do that, but my normal face is just so fierce looking. That and having sex in such a public place would embarrass me to death.
