A few years ago, as newly diagnosed adult, I went to buy clotrimazole cream (cheaper than Canesten) to be prepared for 1 month of wet feet, leading an expedition to Costa Rica in the rainy season. I'd worked there for 5 months through the dry (but nothing is dry in rainforest!) season before diagnois, so knew that atheletes foot was a dinstinct possibilty, despite allowing feet & footwear to dry out whenever possible. The pharmacy assistant recognised that I'd got my insulin etc there recently, but didn't know that I was a registered general nurse, with extensive travel & expedition experience, had written articles and book chapters on expedition health etc, btu I wasn't impressed when she confused Canesten cream for feet with Canesten pessaries for vaginal thrush, as I'd specifically asked for "clotrimazole cream for feet". Not sure she even knew where Costa Rica is (tropical Central America), which is relevent if you're aiming to give travel health advice.
