Clarkson Eyecare

Is it so hard nowadays to go visit the eye doctor for a new prescription?
This is my second year with Clarkson Eyecare and will probably be my last. I do not know if this is how their company does business now or if it was just this particular location. I came in last week for a new exam. They took me back to the small dark room and at first, I thought it was just to take the usual three measurements i’ve had every year. Instead, I was (what I felt or maybe I wasn’t listening closely) tricked into taking pictures of my eye that cost me money out-​of-​pocket. Mind you, I do not have vision insurance in the first place. I’ve never had this done before but the technician who took the pictures said she’s been working with Clarkson for who knows how long and has always done it (while my friend who went to another location was informed this was a «new thing»). But ok, whatever.
The doctor at this location was superb. He was kind and very thorough. I did not have any issues with him.
I went in today for my follow up, and the manager was also very kind. At the end of my visit, the same technician I had last week came to check me out. Maybe she was having a bad day, but I still did not appreciate the service she gave me. I do not know why but my visit this year with Clarkson has seemed somewhat coercive. My previous experience elsewhere has been simple in that I come in, get my eyes checked, then am given a prescription to take home. However, Clarkson doesn’t give you the option to go elsewhere to purchase your glasses or contacts. They end your visit by telling you their prices and you either make a purchase now or come back later.
After she proceeded to write down their prices (and 1 – 800 contacts price because she said they would match it) for me, I asked her if I had to make a purchase today because I did not have the money to do so. She said that it was fine and that I could call back later and just order over the phone. Well, I have never ordered through Clarkson because I can get them through work. So, I asked her if I could have a copy of my prescription instead. She looked at the computer for several minutes before taking out a pad to hesitantly write down my Rx. At this point, she did not seem very pleased with my request. She then went to have the doctor sign it. She came right back only to tell me the doctor is in with a other patient and I would have to wait for him to finish. Ok, I understand that it is rude if I didn’t wait and demanded it to be signed. I would have gladly waited if she did not give me an attitude (or wasn’t so crabby) when she informed me the doctor was busy.
I am not coming back to this location, one — because I did not appreciate the service I was given today and two — because of the way they do business at this location. Why is it so difficult for you to write out my prescription? Isn’t that something that I should be given no matter what? Is this how you treat all of your patients?
