I was obliged to cancel a visit to my dentist because I found the rules impossible to comply with. I have severe arthritis and would have been arriving in a taxi, so "stand outside and wait" was not an option. If this had been the only obstacle i could probably have found someone to drive me there and wait, but the one insurmountable edict was, patients weren't allowed to use the loo. I've since found that other dentists do allow access to waiting rooms and loos, and that they all do their own risk assessments, so rules differ from practice to practice. I hope I don't have to change practices as I've been attending this one for the best part of 20 years, and my dentist is excellent, but if they don't relent about the loo visits then I might have to.
