Bad client service

I always get the worst service from the doctor's rooms. You wait on a que for over 3hours even when there's just 3 people. I'm am soon sick, weak and feeling cold, I have been sitting on the chair in pain for over 2hours while the ladies working there are just chilled behind the counter. They don't even have the decency to explain to the clients why the long wait. What's worse is that, this is not the first time it happened.
