I was flying on QR in business and the shoulder strap, rather unfortunately, diagonally sliced my bosom in half. Although I didn't feel any discomfort a young male cabin crew came over and politely asked if he could help with the strap. It was a good 8 seconds trying to rearrange the strap before he suddenly realized he had over committed himself. I rescued him saying that was fine and could he get me some water. Poor chap he was so embarrassed.
