I guess I'm an outlier. When I see an FA asking about moving personal items (which are 90% of the time computer bags) to keep late arrivals from having to gate check a bag, I offer to place them under my seat next to my purse for takeoff and landing (if it will fit / and the owner will take them in the interim). Usually the offer is declined. The worst part is those same people are almost always the first to hop up when the seatbelt sign goes off to grab those same bags and keep them at their seats. I always hope karma bites them at some point when they reeeeeally need bin space.
