When a client selects a service and a time slot that falls under Premium Hours, they'll see a small note that says Premium time slot right below the service name on the booking screen. If they click on this note, an explanation will pop up clarifying that the service provider has set a higher price for this particular time because it's either very popular or outside of standard business hours. If the client prefers to book at the standard price, they can simply choose a different time slot.
