Long queues yesterday afternoon, priority lane closed, took about 30 minutes to get through. Problem is only one person can unload at a time and if they don't understand what laptops out means, everyone else has to wait until they do get it.
At passports they had 2 officers on the EU side and 1 on the non-EU side. When nobody was going to the EU officers (most of the time, since the e-gates were operational), the officers would signal to the next waiting non-EU passenger, but most of the passengers were not paying attention so nobody moved and the non-EU officer did 3 times as much work as the others.
