Hearing aids are a product, not a medical device, so like any other product people "sell" there are places that focus on the sales, and not the customer experience, unfortunately. It may be the same way with places that sell glasses.
What type of places are you running into this issue? Perhaps Miracle Ear and other places like that? I never went to those places because I did not trust them. I chose to go to ENT office audiologists (though ENT offices can be "sales over care" places) then I found an audiologist who owned her own business and after talking with her, via emails, knew I could trust her because she actually steered me away from buying expensive accessories that she did not feel I needed at that point. I was very happy with her as I knew she cared about providing me with the best hearing, not the sale of the hearing device. Eventually I became a CI candidate. She even went to the trouble & expense to get set up to program the HA that worked with my CI. I'm bilateral now, so I have had no reason to visit her since 2018.
