I think there was an airport type scanner. Not sure if it was switched on. Certainly no-one appeared to be watching it. I was asked halfheartedly by a steward if I had anything in my pockets which were full of keys, phone etc and they just let me wander through. All that metal didn’t set anything off.It sounded loud from where I was, lower tier 125.
Bars are always closed straight after the game, which is another reason why the Amex is unique.
Which level were you on? I had to walk through a security gate similar to an airport scanner, which is far more secure than a wand. It did ping because I am wearing a wrist splint with steel in it, but it’s fairly obvious by sight. My other half did get patted down, when he pinged the scanner.
I also had my bag searched.
