A couple of pointers
1. Use the forum and do as much research as possible. Come up with a list of places your interested in visiting. This site gives you locations, physical descriptions, donations, and what you expect.
2. No need for advanced appointments, call 30 mins to 1 hour before your ready to walk in.
3. For the call, ask how many girls are working, if you have a name in mind, ask if shes available.
4. DO YOUR RESEARCH.
5. If the girl you want is available, ask for an appointment, tell them your on your way.
6. If the girl you want is not available, notify the MMS that you want a line up when you come in (chose who you like) or call the next place on your list.
7. As far as service goes, read reviews, do your homework before hand, during the massage let your hands roam a bit and see if they stop you or let you go.
8. DO YOUR RESEARCH.
