From my experience of having to visit many doctors in Tunisia, I can say there is no wait at all for a doctors appointment, you may have to wait if there are people wanting to be seen too on that day but actually its a case of walk in and get seen - not an appointment only service like my doctors in the UK, I do remember the very first time when I asked my fiance to ring and make a doctors appointment for me, he just looked at me and laughed and replied 'its not the UK' I still made him telephone the doctor and the receptionist said come when you want .
We had appointments and some doctors offices keep them and some don't. I usually learn from my bad decisions about them. Some I will wait well over an hour or more for one appointment. Now, I have great doctors for the girls. They always can be seen right away. Emergencies do happen sometimes, don't they?
