"Unprofessional medical practitioner"

I had an appointment for tests at the Connaught Square practice. The reception staff had a good Covid19 safe system in place but the person I had the appointment with was wearing a loose face mask which was only covering their mouth most of the time. Sometimes they popped it back up over their nose when they saw me staring but in general the way they were wearing it was not safe, and the appointment was in a very small room and required physical contact so they were right close to me.
