.. just my opinion, but in South Upper there are about 30 rows of people from back row down to the vomitory exits. Seemed to take a long, long time for folk to plod down and out.

Also seemed a bit odd that the chap giving the evacuate message:

a) didn't say it was the evacuation exercise - just Operation Everton or something.

and b). after first time he made the announcement he said he was just kidding.

Not too professional to say it was probably being observed by whoever gives the certificate.
