I HATE (as in hate hate hate) putting on wet or even damp bike clothes. Is there absolutely nowhere you can hide your damp clothes and let them air? This isn't the sort of thing people steal, so as long as you're not annoying anyone too much they will probably hang there in peace.

But if I had no place to air my clothes I'd bring an extra pair of shorts and maybe socks. Jersey/jacket I'd air over the back of my chair wherever I was sitting, that's socially acceptable

PS. You can also "dry" shorts by turning them inside out and wrapping them in a old absorbent towel. But then you have to carry an extra towel. Faster drying minimizes smell, though.
