If it hadn't been for that sign, I'd have been hawking (yes, that word again, it means bringing up phlegm) and scything through my undergrowth with great enthusiasm. 'No spitting, no shaving' has been my favourite to date (at Tooting Leisure Centre, for completists). The signs pool management need to put up in changing rooms usually give you an idea of the kind of thing patrons would be up to, if they could. And having once got changed out of a wetsuit in a minibus with nine other people I hardly knew after a swim in a glacial lake in freezing rain, you'd imagine I'd be loth to moan about basic facilities.
I've been around long enough to see 'progress' that sometimes doesn't feel like that. I've also swum where there were no changing rooms – it's the downside to 'wild' swimming (or upside when you consider the state of some of them). I 've been to many changing rooms in my long and (ahem) illustrious swimming life I hope I have seen the worst and suspect I'll never see the best.
