I would say yes, but in fact, an experience recently makes me think that perhaps no.
I reside in France and had to go to an opticians. The shop typically looked high class and I hate the brightness of those places, but I need glass for short distances and so, my husband and I went in and I zoomed in on a pair of glasses that instinctly told me they would look ok on me and my husband said: check the price first, as I am pretty sure they are going to be way over our budget. Wow, only 30 euros lol
The assistant offered me a pair of sunglasses and even asked if I have sensory issues and thus, explained the brightness causes distresses and so, she got me to choose the ambiance of each colour and I picked on a beautful brown one and she did a lot of typing and then, turned the computer around and my husband and I did a double take: from 30 to over 300 euros! My hubs explained that he is only a gardener and just cannot afford that, she she deleted down to a smaller number which is accident insurance, but he asked her to cut that out too and thus, I ended up paying the original price and guess what? Her tone of voice and her facial expressions did not change at all. She maintained a polite, friendly that she had from the start and I confirmed this with my husband.
I want to give her a card of thanks actually.
But, in fact, that is a rare occurance, since sadly glass distinction is in every country.
