In response to your post norodnik, It becomes clear to me that you to don't listen to or read the saftey procedures on board the aircraft.
You mention about how the crew should emphisise the 'big' exits as the pax using the 'small' exits would all be fried! If you read the safety card, it clearly points out that you DO NOT open the exit if there is a hazard outside eg fire or smoke! So it is perfectly safe to use the 'small' exits if there are no hazzards. Eg on a 737, the only usable exits in a ditching are the overwing. So may I suggest in the politest possible way, that may be you too should pay more attention to what is being said in the safety demo, and read the saftey card in the seat pocket, as it is there for your safety!
Sorry if his sounds blunt, but we are all guilty of not listening.
