Last Wednesday I went to the dental surgeon for a short consultation. I would like to say something about this, especially to allow other patients to benefit from it. I had an appointment at 11 am. I immediately went to the desk where 3 ladies were and was promptly called in to take a photo. Then I had to wait until 12.15 before I saw the dental surgeon. That can happen but what I am mainly interested in:
When making an appointment, indicate that it may happen that emergencies come in between. Then indicate at the counter that urgent matters have come in between, as a result of which the appointment is delayed. After half an hour, indicate again how long it will take. I think it is not normal that you wait 5 minutes for an appointment and that while you are waiting you see the 3 ladies chatting, they were certainly not busy. In short, all the time to inform the waiting patients. If I had heard that it would end at 11 am, I would have chosen to come back at another time. It is also important to realize that there are people in the waiting room who are nervous about the procedure that awaits them, not nice if you have to wait a long time. In short: explain, and again, that gives understanding and therefore patience and no angry customers. I only heard it when I asked for it and then got angry because I wanted to know before.
