remain seated
>>>Because it is often faster, and evacuating people over baggage that has been removed from bins is pretty tricky - not as many things to grab a hold of if it stops quickly either.<<<
I'm not sure there have been many evacuations from a/c arriving on stand in circumstances where people can see they're 3 metres from the gate and their ordeal is almost over - what are we being protected from at that time. Air travel is just awful and it remains a delight to stand as soon as possible rather than be couped up for another second so I doubt an in-joke-hissy-fit on the p.a. will change anything. It's a while since I've taken bus or tube but these were full of bags etc. the last time I endured it.
