On my flight this morning after takeoff, a women sitting on the isle, I was sitting by the baulkhead window, first takes the barf bag, and puts it on the middle seat. Then she takes the CO magazine and starts tearing page by page and puts the cut pages in the bag. I am sure glad I changed my seat on check in to the baulkhead. I should have kept the seat I selected when I booked the flight. Also, the women wanted to use the first class Lav, FA said no, have to use the ones in the back. She was complaining for the rest of the flight about this.
