Just a little heads up if you are coming to the UK. Many public toilets charge as much as 50p to access them.
We are in Fort William in Scotland. Female toilets open but I didn’t have 50p. Plus I object to paying for it! Also of note is that the disabled toilets were locked! So double whammy if you had mobility issues and no coins. They also don’t give change so if we only had a 1 pound coin my husband could go but not get change to pass on to me!
Not good!
