Hi Munger - welcome to the forum and thanks for your first post!
Don't worry about language - you can take a pen and small notepad with you if you want ... when I'm travelling I always carry one for communicating with but have never needed one while mongering.
Price hasn't been an issue in my experience - it's pretty standard and they know what they advertised. I just walk in and leave it to later.
A few girls do get pushy about tips,
but it's up to you if you feel you got what you were wanting. If you like you can ask as you walk in - in English, or try saying "bay chin" - language isn't an issue, she'll probably just reach for pen and paper and write a number ... or if you just hover outside the door as if you're hesitating you'll probably find she has all the vocabulary she needs to try to reassure you about what you'll get and how much for!
Stats - of course many are shorter or fatter than you see in the pics - but fewer than you'd expect. Rather more common is the color on their pics may have been lightened (Chinese like fair skin). You occasionally see reports about a switch - another girl using the room - but that seems pretty rare too. If you don't like what you see,
don't go in - they're used to rejection too, especially the ones that you'd want to walk away from!
Hard to give you a recommendation - so much depends on your taste and predilictions
- I'd recommend you search the db for girls close by (shouldn't take long, there aren't as many as TST or CWB), pick a few you like the look of, then use the search function to find reports on them. Much more fun that way as it builds the anticipation!
Good luck, and post a report.
