I swim at my local gym/pool regularly this year. They have a lane system where adult only members book online or turn up at reception to see if there is space, and book the lane speed that suits them slow medium or fast.
Each lane is sectioned off and has instructions of which direction to swim in each lane - up one side of the lane, back up the other side. You have to move over about 1-1.5 meters at each end of your length of swim to start your next length. It’s no hassle to do this tbh takes a second or 2. I always pick the slow lane which has one side against a rope and the other side is the pool wall.
The central rope side you will always get splashed by people in the faster lanes but it’s not a big deal. I swim to the rules, trying to time match others who swim in my lane to give them space so I am not getting too close to them or if they are a lot faster, I will let them go off before me.
I go at mostly quiet times and almost every time if there is only 1 other person in my section they will either ask me if we can just swim up and down in a straight line and they will ALWAYS be asking for the wall side, or they will just start swimming up and down against the wall and not say anything. If a 3rd person joins they will go back to swimming in the right direction. Not the same person, always different people.
I am a self taught (as adult) swimmer who isn’t that confident in the deep end so I choose to swim in a lane that isn't just in the middle of the pool. I’m not insanely slow but there are other lanes to use if you are a faster swimmer!
Recently I said no, sorry to someone who asked me to swim in the middle of the pool as I said I was still working on my confidence and they laughed and said I ‘seemed fine’. I didn’t ask for just the wall side, I said can we just swim in the rotation as per the rules? If they told me they felt worried and wanted the wall I would have let them tbh, but they didn’t.
AIBU that the directional system is fine and this way it means everyone gets to swim near the wall for one length if they need/want/like to?
