I had a lady with tummy band and arm bands who was sort of thrashing about and moving about 1m an hour, she shrieked when I over took her (at the end of the lane, she'd stopped so I went ahead). It was just plain weird, specially as she was in the fast lane, not sure what was going on there really.
What I really HATE though, is when you are swimming lanes and you get two (usually but not always) women just stood at the end, in the lane, talking. There are 2 particular ones when I go that stand there for half an hour, swim about five lengths inbetween then stand there again. They seem to be really great swimmers too, so Its not as if they are knackered and need the rest. So annoying. And what a waste of £3.00 as well, why not just go round for a cuppa and chat??!!!
