Dude, just go into any of them! I remember I went to what I thought was a veggie place and all that was separating the other beds was a curtain. Eventually I got excited and she sucked my dry dude. Swallowed and all. It was BEAUTIFUL. I don't even remember how much she asked for a tip. Does 1000 seem legit? Don't remember the currency but that number jumps out at me......Lost in my memories....
Anyway, yeah, just walk by and pick a girl you like as they all stand outside waiting.
