If I'm playing out of a bunker, and my ball doesn't get out, can I rake the bunker in between shots?
Not if doing so improves your lie, or your stance. If the ball rolls back into your footprints, that's just tough luck. If you have to stand awkwardly due to your previous footprints, that is also tough luck.
I wish all of these covid golfers would learn to use a freaking rake?!?!
