On Wednesday of this week, UA SFO-SEA, we were landing, gear down, and the guy in front of me gets up to use the head. We had to do a go-around and some of the pax made comments to the guy who used the head when he came back. That guy looked like he could have been insane, seriously, so I kept my thoughts to myself. No "rage" really ever ensued but I think it came close.
