.....and you get to see the same doctor every time!
To be fair to my practice, they do have a walk in every morning between 8.30 and 10.30am but you can't choose which doctor you see and you have to be prepared to sit there for a long time.
You can only make an appointment for 2 days in advance and you have to phone at 8am to make one. If you can't get through, then by 8.15am all the appointments have gone.
