Here’s what typically happens - they hire a new girl, perhaps attractive or maybe they can market her as younger than she really is because she’s somewhat cute. They start posting bullshit “reviews” that draw in more customers looking for the services they are shilling. Customers probably walk away disappointed, but there are plenty more. The girl either eventually caves to the pressure from so many requests and additional money being offered, or she quits. If she stays, the shilling for ever-escalating levels of service continues and she is pressured for higher and higher levels of service. Her repeat customers think they must be missing out, and keep coming back. The spa can always just hire a new girl if she leaves and the cycle begins again.
