OldLurker,
Just so you know, if we are ever on an aircraft and the slides are thrown and a emergency evacuation is ordered, you will be getting of my way if you are farting about looking for you hat coat, bag etc. If that means i have to go over the top of you or through you to get out that is exactly what will happen.
It is called a emergency evacuation for a reason, it is never routine, if the cabin crew are instructing you to get off, that is exactly what you should be doing, no passenger on that aircraft was capable of making an assessment on the fire risk etc. I would rather be on the tarmac feeling cold than frying to death because some selfish sod was trying to wrap up warm before exiting.
