Dentist Asmall if you feel like wasting your time!

It's the the third time I and visiting this dentist that " makes appointments" but fails to stick to his time...yes 10 even 20 minutes I can understand but every appointment it's at least an hour to and hour and half wait...it's pathetic! And the staff has a don't care attitude...they can't answer the questions must speak to the dentist...for what the hell are the employed?
