Or someone opening up a compartment door only to find their space already way to full
On a recent flight, I got to my row and I was the first person to reach that row on either side. I opened the overhead bin--it was full. So was the one on the opposite side and all the ones adjacent to it. There was no one sitting in row 9 at that time so I knew the stuff didn't belong to anyone in that row. I asked, "Whose stuff is this?" No one answered. I told the flight attendant that my bin was full. She said there was plenty of room in the back bins and I could put my stuff there. I must have gone back at least 9 rows to put my stuff. I wasn't happy.
Plus, one of the bags in the bin over my head didn't fit well and the lid had trouble closing. In fact it popped open while the plane was moving. Attendant saw it as she was sitting down and came and closed it.
At end of flight I had to wait for people to leave to go retrieve my stuff. A couple people from zone 2 came to my
bin and got their bags and one guy from way in the back quickly walked down the aisle and grabbed his bag from my bin. I said something to the flight attendant about that. She said he shouldn't have put his stuff there. Duh.
No wonder there was room in the back bins. People who had those seats had put their bags up front.
When I get a seat assignment, I get first dibs on my bin. If it's full because other people in the row have their stuff in it, that's one thing, but it should not be full because people want to be able to get off the plane quickly.
Next time I'm just going to take their stuff out.
