I did mine years ago - nah nah nahnah nah
- There was a point at which we were told to remove jackets, whilst in the pool, and swap with another "bather", to which I said "No thank you" or alternative words to that effect. The drills may have changed since, though. Female cabin crew in wet uniforms is a definite bonus.
As was dragging the Fleet Manager into the dinghy by grabbing a chunk of skin - he did'nt half squeal !
I've learnt how not to drown since then ("learnt how to swim" is going a bit far). I recommend it !
