This seems so simple that it should be obvious, but it apparently it's not, so I guess I have to spell it out. When waiting at a baggage claim carousel, you should stand back a few feet until you see your bag. Not only does it make it easier for everyone to get a view of the bags, but it leaves room for unloading the bags. Don't crowd the carousel like these people:
One guy has the right idea, but he can't see the bags that are coming because the others are blocking his view.
On a recent flight I saw my bag coming around , and had to squeeze my way through the people crowding the carousel. When it came, I grabbed it and lifted it off in order to put it on the ground. In the process it struck one of the people crowding the area, and he gave me a dirty look. I gave him one right back. It's simply rude not to give a fellow traveler enough room to retrieve their luggage, and when you see someone grabbing their bag, it's up to you to get out of their way.
