1. What I like about Summerville. Well run, roster up a week in advance. With many visits, only 2 problems: one the girl never came to work again. The other, the receptionist never caught the girl's later start time due to school starting. Otherwise, solid. I'd say a distinguishing characteristic of a good shop is a known roster: girls appreciate working there so less inclined to move without notice, last minute no-shows, etc. At least a shop should know what days a girl is scheduled for and let you book, messaging you beforehand if there is a schedule change.

2. Why I get her WeChat. Even if she can't book the appointment herself, she obviously knows her schedule so you can call several days in advance, and if there is a problem, she can let you know.
