Most people here don't do this shit weekly, so when they get an opportunity even if it's not great and they've already sunk in cost and effort, they'll go along for the ride regardless. So the one or two people in a week who leave may feel good for themselves, the majority of the money still ends up in her pocket and she thinks you're the asshole not her. Write reviews and don't see her, but she'll still get hits and she's most likely not going to change. But don't blame mongers for seeing her because her price point fits their needs and they saw shitty reviews and went anyway. Just say I told you so and move on when they bitch about services they knew would be less than amazing.
