In the UK we have a free health service. Payments to doctors are conditional on ther meeting set targets .. one of which is that every patient is seen within 24 hours of making an appointment.
So when I need to see a doctor (I do) I have to queue up at 8.30am to make an appointment .. and if I don't get an appointment (within 24 hours) I have to queue up again next day..24 hours later.
