In the comments section of a video I watched recently, it was brought up that there are grocery stores which offer free pieces of fruit to children of shoppers. I noted that I had seen that at Kroger, a supermarket chain based in Ohio. Since a number of people hadn't heard of that, I decided to take pictures when I visited Kroger this afternoon.
It only had one banana when I was there, but they have bananas and I think clementine oranges or apples. I don't know how common it is, but I wish more stores would do it.
