I'd love to know where the patients got the referal, that's going to be a whole story in itself.
You'd be surprised how daft women get if they think you're doctor. One of my credit cards has "Dr" printed on it instead of "Mr" by mistake & it's remarkable how many female cashiers & suchlike go all "funny" when when they see it.
I've not been asked to perform any medical services but I have had to explain that I'm not in fact a medic on a few occasions when someone starts telling me their symptoms etc, etc.
