When my wife needs to see a particular doc because she has numerous problems and it would take at least 30 mins for a stranger to get up to speed.
If urgent she will see anyone but - urgent - is usually hospital.
I go to the docs - can I see "X" - NO.
I will be prepared to wait a week two weeks three weeks - NO.
You have to go home and phone each day at 8.30am and hope you beat others to the appointment.
This way no one waits for more than two days to see a doc -on paper!!
It is madness!
