Ironically enough, we eat a lot of grapes in my house, and I legit had no concept of people doing this until about 3 mos. ago - was at Kroger in Oxford, and as I was walking up to the grapes I saw a super old guy reach in a bag, take one out and eat it. At first I thought WT17 is he doing, and then I thought ahhhhhh ... as someone who's been the victim of a bag full of not-so-good grapes, it felt like it was a genius, baller move. But I can't bring myself to do it ... and I always wash all of them off and stick them in a bowl in the fridge when we get home.
