Sat in my seat during boarding just now in 2F and the guy in 2D put his bag under the seat infront of 2E. Interesting, I thought. Then 2E pax arrived, saw the bag and turned to 2D pax and asked if it was his. 2D said yes and that he couldn't fit it under his seat. 2E just looked at him with a look that suggested he had a very good idea where he could stick the bag. Hilarious. 2D seemed oblivious and thought it's all open for grabs. 2E ain't no shrinking violet either!
