There is a hobby I do with a few friends and every so often we go to a new site. This site caters for individuals, family groups so it is busy and there are people of all ages and experiences.
Essentially, there is a male changing room and a female changing room just off of the main lobby area I was changing after my session had finished and quickly noticed there was an issue with the door being opened every time someone entered. It meant people walking past could see in almost without helping it, and us inside were pretty much in full view. There were young girls in there who became aware of it who were already changing/had towels wrapped around themselves etc.
I am wondering whether it is worth emailing them to raise this as a concern re the privacy of people in the changing rooms (e.g. add a double door or similar) However, equally, don't want to be 'that person' and happy to be told it is none of my business and anyone there will just be getting on with their own activities etc.
