You wouldn't believe me if you saw me now but a looooong time ago, I got a full-time job as a lifeguard in a swimming pool in a regional town close to Dublin. It was a public service/civil service job 'n all.
Anyways, when the travellers visited the town on their summer travels, they used to pay to come into the swimming pool. Not for swimming. They used to bring in their clothes and wash themselves and their clothes in the showers!
I never really liked public swimming pools because, well, the public use them...
