At a French Campsite Ten Years Ago

Ten years ago, my family and I stayed at a French caravan park near Paris. There was a rule that you had to take your shoes off and put them on a rack before going in the shower block. The idea was to stop mud appearing on the wet floor inside.

At the time, I thought the rule was a bit weird. I had never come across that before at a caravan park and so at least once I ignored the rule.
