Yes and no. I do believe that expectations should vary depending on the type of establishment but certain minimums should apply to all. If you go to a very upscale restaurant where a typical dinner is $50 or more, you will be expected as a customer to dress up, act accordingly, etc. At the same time you will expect the staff to treat you like a king/queen because you are spending that kind of money there. Establishments do also have the right to set house rules governing what type of dress code is required (formal, casual, etc.) and what kind of behavior is expected.
However, certain minimums are expected for all customer service even at the dollar store or the 7/11 or the dive bar. You are choosing to spend your money at their establishment instead of one of their competitors. You aren't required to spend money there even if it is just a few dollars. Even 1-star and no-star establishments should still have reasonable professionalism. As long as you are abiding by the house rules (which should also be reasonable relative to the price paid) if a problem arises it is the management's responsibility to take care of the customer's needs. People wonder why bars and restaurants suddenly go out of business. This is partly why. They take the large crowds of people for granted but then when the service quality drops not only do a number of them stop going they quit bringing their friends along as well and the whole thing snowballs.
I also think that as trans people we deserve equal treatment to non-trans people. We have dollars in our community as well. I think it helps the trans and trans-allied public to know which establishments value our business and want our money and which ones need to be exposed for what they are. It really comes down again to free market economics. A business can choose to be a lousy place to go. I also can choose to tell everyone how horrible it is. Isn't freedom great? I'm doing this because these days bad customer service is becoming more of the norm than the exception. It is time to change that especially when it makes it even worse on the trans community.
