Were these take at the far end of the airport near the Vallence collection? If so, you were lucky to get 20 minutes. I was there last week, and got moved on after only 2 minutes! by the police.
Not today, they were taken on the inner perimeter road by the terminal.
It’s strange they moved you on. Did you have a car with you? If so, then you will definately get moved on. By foot, i’ve never ever had a problem. There were about 10 or 15 of us today and all the security teams do is drive past 🙂
Thanks for comments everyone 😀
