But its 6 of one and half a dozen of the other.....
Looking at this in a purely selfish manner, Airside staff pay overinflated prices for hot meals at the moment and don't have time to sit down anyway and there is little takeaway choice. You are unable to have for example a BK Meal from landside as the liquid restrictions hinder transition, so you end up paying more for a burger and fries than the meal deal itself! Also operational staff dont have time to go through security and a lot of these staff have to be airside at all times!
