floatation devices

i’ve been in two places in the last few days where the wearing of floatation devices was a possibility. in both cases i’ve considered putting my life jacket on prior to an emergency so as to be ready in case the unlikely event happened.
jane, my wife, suggested this might cause panic on both the airplane and touristy canal boat so i left them tightly packed away for their own safety under my seat.
it seems community police(wo)men have opted for the safe approach. here are two with their life jackets round their backs. they were also quite reflective of my camera flash.
