What annoys you?

Please tell me that this kind of thing doesn't happen in the States! This morning, before coming into work, I trained at the local pool in Kenilworth, England, - 25 metres, four lanes. Not brilliant facilities, but acceptable. At the end of each lane there is a sign: lane 1- slow, lane 2 - slow, lane 3 -medium, lane 4 - fast. Why do some swimmers, who clearly have difficulty in keeping up, always want to swim in the fast lane? This morning one elderly man, joined the fast lane. He swam breaststroke (I think it was!) with his face out of the water, which was a feat in itself because he was swimming so slowly. There were six of us in the lane and three left the pool (myself included). When on the deck I decided to time him. He was consistent. Every length of the 25m pool was swum in 2 mins 15 seconds! Please tell me this kind of 'swimming etiquette' wouldn't be seen in your pool. So that I can continue with my swimming I need to be reassured that this was a one-off. I'm still in shock.
