I read the card (so I make sure that it is there and would ask if it is not but it always has been there).
I watch 'the dance' because some life jackets are tied at the side and some in front (Velcro anyone?)
I check under my seat for the jacket.
I count the rows to my exit.
I look at the pax around me and try to guess who will 'freeze' and who might panic and who will simply block my route due to the sheer bulk of their personality.
Just another bloke who has been self loading for 38 years and reckons he would like to continue doing so a bit longer, even though he has never experienced anything so much as an RTO or go round ...
