I guess it's on topic.... maybe not....
A few weeks back in J on HKG-DFW I walked on the plane and loaded up the bin directly above my seat. I then realized I needed to get something out of my suitcase before take off so once the boarding traffic slowed I stood up to get it down and get what I needed out of it. The guy sitting across the isle jumped up quickly and placed what a small bag (looked like a computer bag) where I had removed my suite case. I made the comment that my bag was going back in there to which he didn't respond. Once zipped back up, I turned to him and said "hope that ain't breakable" and put it back in its spot (except now it was on top of his bag). I probably wouldn't have done it if it were not for the fact that he pulled his bag out of the overhead directly above his seat and threw it in mine the minute I removed my suitcase. Oh well.
We should have a thread for Overhead Bin complaints. Maybe this is it!
