I do agree with @EarringsandLipstick here.
My DH is called Mr Carl Smith, and we live at 3 High Street Chipley. WN5 3LL.
He was born 12/12/1964.
He gets his meds from the ONLY pharmacy for 10 miles.
There is a Ms Carol Smith, who lives at 3 High Street, Chippen, WN5 4KK. A village a couple of miles away from us.
She was born 1/12/1964.
It's a scarily similar name, address, and birthdate! He has been given Ms Smith's meds a few times. She has probably had his too, but as his has always been there when he goes, I assume she gives them back! (As does he!)
Hasn't happened for several years, but happened a good 8-10 times for the first year we lived where we live now!
So yes, pharmacies do have to be very meticulous!
