actually you guys are comparing daily rates which normally will be expensive...in any businesses prices shoots up as long as you are inquiring on a one time basis...
Except for Barfines and those that are Super Angpai or have "big fishes" coming to look for them, Im pretty sure there are many girls in Patts that are willing to lower prices if you ask upfront for extended period...even for those that have to go back early to their hubby or gigs or whatever, they still come back in late afternoon or evening time to join you...so in short even for Agogos in LK or WS, I believe 1.5K~2K for LT is still doable...but of course for places like Super, Happy and others that have policies to pay full upfront, than you lan lan have to pay first time but the next few days if you stick with the same girl, chances are high you could nego down with the girl on the LT
Treat the girl like a whore you pay whore rates, treat a girl like a friend or gf, then sometimes you be pleasantly surprised
But if you have super BO smell or are unruly, sadistic or obnoxious person then best of luck to you
Oh btw there are some gogo bars that practice new approaches by lowering the LT but marking up on the barfines..so best is that you nego on total package instead
