Or Sydney Opera House maybe? The old BA lounge WAS an oasis of tranquillity! I was also on the verge of passing out due to the temperature in there a couple of weeks ago.
As soon as I enter the security queue at MAN I ask the nearest member of staff what they require removing from the bags on that particular day as it changes on a daily basis. But who packs a hairdryer these days?! (Mind you, my OH often gets questioned when he carries an actual digital SLR camera, I think they assume everyone just uses their phones now).
