Toggle the "Do prices vary by staff member?" to yes.
Then you can then set up prices for each staff member within each service on the Services Menu
My Business Name > Business Setup > Services Menu.
Click on the service and Edit next to the Regular price.
Select your employees and add their prices and happy hour pricing. Don't forget to save your changes.
