I'm a regular critic of the facilities and service experience at MAN but I speak as I find.....on my first two trips so far in the New Year I can honestly say that I have been through security in less than 10 mins on both occasions with no dramas - of course it's the quiet season but it shows what can be done.
I'm still not fond of the 'threats': 'you will be delayed by 30-40 minutes' that sounds like a policy to me - which would be unacceptable.
By the way the shouting has been toned down somewhat in recent times...maybe they read this stuff and have moderated their nonsense. However if you really want to hear some full-on security queue shouting, try any US gateway airport. They are the masters at that.
