What really peevs me off is when approaching the gate all the mainlanders get up and these little petit humans try unload their 20kg+ carry-on luggage before the final brakes have been applied and the seatbelt sign turned off - when brakes are applied that 20kg with added 'g' will snap someones head off one day. I would often call the closest CA and ask - ' what the hells going on' - that seems to get some attention.
