What kind of danger is involved in an evacuation please?
As above... + potentially paralysis
plus the chance of being run over by a fire truck, or any of the many vehicles that will be milling around in the dark.
The escape slide experience isn't a fairground ride.
It "appears" that there was no evidence, or immediate danger, of a fire, ( tho' of course I wasn' there ) so sit back, have another drink Sir, nobody's going anywhere in a hurry.
