Session times have changed because of the school holidays. There's no lane swimming during the day, only general swimming, which is making the early morning and evening swimming very busy.
My friend is a big man, well over six ft (ie takes up a lot of space) and a very good swimmer. He's gone into the fast lane and done his thing. There were two women also there swimming much too slowly for the fast lane. The target times for a length are published, so fast is not subjective, although they didn't appear to be aware of this.
Anyway they've objected and said they think he's very rude to be ploughing up and down. He thinks that's what the fast lane's for....
