Better safe than sorry
Us Brits are good at it, we just accept it. I am talking about queueing.
Who would want to be stuck for 10 hours on the motorway trying to get a ferry to France. At the airport I noticed checks were taking longer and the queue getting bigger. We waited for our turn with no fuss until someone decided to have a go at a supervisor as to why it was taking so long.
I would rather security take as long as is needed to make sure there are no threats on board the plane. It’s better to be safe than sorry.
