All savvy business owners would protect themselves legally and financially. They would also have their customers best interests in mind which would keep their customer base. Escorting would be no different. That is just smart business. I would not consider them to be running a bad business plan, nor would I hold it against them. Again, an escort would be no different.
In any business, they choose their hours of operation and hold the right to refuse service to anyone. They also choose a location that would bring in the most business. Once again, an escort would be no different.
There are many risks in any business. An escort has even more risks to face than the average business does. In my opinion Misty handled her situation and risks quite intelligently.
