People are like sheep, it doesn't matter how many times the fire exit doors are closed someone will open it within seconds and then passengers queue in an orderly line to enter or leave the terminal despite standing next to the automated doors. Always interesting to watch someone who has a full size case in each hand battle to get into or out of the terminal when the gap is only around a metre. Oh and in the background can be seen just one of many smokers trying out their new unofficial smokers shelter. I have already had a moan about it but was told that as soon as people are moved on a new group forms so they have given up trying to enforce the ban.
