complaining about. I was sitting in the exit row, and as I was walking down I could see that all of the bins above the exit rows were already full and closed (the exit rows usually have people with status who get to board first). So I put my roller in a bin that was 2-3 rows in front of my seat because the only other alternative was one that was several rows behind my seat, and I didn't want to have to go backwards.
Maybe a jerk move by me, but there wasn't any place above my seat to put my bag so I had to find open space.
