I have about 800k lifetime miles and see this on every flight. A lot of people do put their bags right next to them. A lot of people also drop it off on the first space that is available to them. When I had status I used to sit in first class a lot. Some people try to dump their bags there, but get yelled at 100% of the time. People really love opening the bins for the people in the first row (no under-seat storage because there's a bulkhead; bins closed to make them less attractive to the dive bombers), but also usually get yelled at for that. I have even seen this happen way in the back. I was sitting in row 21 or something and someone sitting in the last row put their bag right next to mine. Chuck it in there, walk to the back. Hope they put a passcode on their iPad! I used to fly JFK-SFO and JFK-LAX a lot. Not sure I saw it as much on those routes.
