For such an expert, you're going to the wrong places. Shangri La used to charge 80 until demand got great with all the talent lining up to work there. Extras for the most part are YMMV between the customer and attendant. Some guys may have to bribe or coerce the girl to do more, especially if she's desperate and hasn't had enough business for the day. Only one girl at Lavender asked for more, actually the rest never asked nor look at how much is given, they just smile, give a nice hug and or kiss goodbye and say please come back soon. And I do. All the extras listed above have been included depending on comfort level of each attendant. I for one would never pay on an a la carte type menu. If she wants to provide the "service" which is a mutually enjoyable act she will. Asking for more for anything just says I don't want to do it with you BUT if you pay 20, 30 40 extra I will you ugly disgusting POS lol
Again, just my humble opinion from what I observe.
