Seen them at the pool. Two ladies walking up and down the lanes with a lane rope between them. And they happened to choose our lane to do this in.
The standard rules for a lap pool is you keep left, then turn, then keep left again. Not march up and down the lane chatting to your friend. I tried to swim towards one of them to hope they would get the message, but they kept marching up and down, up and down. Obviously having no idea that they were doing something wrong, or not even caring.
Huh. I can see how that would work if everyone was swimming, and swimming at the same speed, but not if there were slow swimmers/walkers - wouldn't that just lead to a back up/bottleneck behind the poor person?
My exBF and I used to go to the lap pool at a gym, and the rule there apparently was "stay in your lane" and that was it. First come first serve, unless you could negotiate sharing a lane with another swimmer with similar skill or at least good timing.
We had hardcore triathlon swimmers training next to senior citizens walking back and forth before they went to sit in the hot tub or sauna. I can't imagine how the "turn/keep left" rule would have worked.
My friend and I did the walk and chat (when no one was waiting to use a lane) during the second half of our time there, because going to the gym was one of the only chances we had to socialize and catch up with each other. Also, talking to each other helped distract us from the exercise so we could push through and since we were entertaining ourselves it wasn't such a slog. We talked in the pool for the same reason people listen to music while they walk or jog. Sometimes since we were going at the same speed and talking to each other, we could share a lane and let someone else have the other one.
The only thing we found annoying in the pool (besides the lack of lanes and lane ropes that were too loose) was the swimmers who splashed everyone.
