Its all well and good in theory but the reality is that fat sweaty northern bloke will have his pits in ur face blocking you in trying to retrieve his measly belongings them 2 brats who were kicking your seat for the past hour will be screaming and climbing all over the place. You will be in so much shock and fear that the lifejacket and the safety information you thought you understood will look as complex as a rubix cube
Best just to not be unlucky
