You ring for an apt,you get one. You appear to make an apt you may get lucky as a walk in. It all about your demeanor. If you look like an urgent need to see doctor, the staff assess your needs relative to the available Doctors. Once you are an established client it goes smoothly. Apt times are given..its up to you to come on time. If you have to pay then you have to pay. Life's like that.accept that with manners. Staff have to be neutral. Its not fair. It the way it is. Live with it or go elsewhere.
I travel past 20 or more Doctors to go there. Its my choice.
