Where must a sign that reads "price list available upon request" be displayed?

The display of a sign stating "price list available upon request" in both the reception room and work room aligns with the regulations concerning transparency in pricing for cosmetology services. These areas are where clients typically interact with staff and would naturally seek information about service costs.

Having the sign in the reception room ensures that clients are informed as they arrive, allowing them to inquire about prices before making any decisions regarding services. Additionally, displaying it in the work room is beneficial because it provides easy access to this information while clients are receiving services or are in proximity to stylists, facilitating an atmosphere of openness regarding pricing.

Choosing other locations, such as the restroom or at individual stylist stations, would not be as effective for clear communication with all clients, as these areas may not readily allow for easy access to that information. Placing the sign at the main entrance could also limit its visibility during client consultations and interactions. Thus, the reception and work rooms are the most appropriate locations for such a sign, ensuring that clients can easily see and request the information.
