I assume you meant to ask if it is appropriate to ask your massage therapist to keep their prices transparent or visible, rather than "uncovered."
Yes, it is entirely appropriate to ask your massage therapist for transparent pricing or to keep their prices visible. In fact, it is a standard and reasonable request that customers make in any service industry.
Clear and visible pricing is a sign of professionalism and transparency. As a customer, you have the right to know what you are being charged for and how much the service will cost. This information should be readily available to you, either through their website, brochures, or posted in their place of business.
Asking for transparent pricing shows that you value honest and open communication. It can also help avoid any misunderstandings or surprises when it comes to the cost of the massage service. If a massage therapist is reluctant to share their prices or seems hesitant to provide this information, it may be a red flag, and you might want to consider finding another massage therapist who is more upfront about their pricing and business practices.
