I go to my local SpecSavers and have done for the last 15 years.Yes they are always busy , and sometimes there is a time delay in seeing the optician, but I have never felt rushed, or made to feel uncomfortable if I asked any questions.
They do all the routine testing , peripheral vision, pressure, and photographing the back of the eye.
As others have said, if you are not happy with the service of your current provider, vote with your feet and go elsewhere.
Ask friends or family for recommendations .
