To begin with, let me compliment the members who have posted sarcastic replies ... really amusing
Now to address yo yo's predicament.
I find it difficult to understand why you do not want to go to a SB/DB/OB and select a girl of your choice.
Suppose someone does give you a number, how can you be sure that you will like her and her services?
Anyway, let me suggest another option ...
Go through the last few pages and approach the lodges mentioned, directly.
If you are lucky, they may arrange someone for you.
There are other lodges also that provide these 'settings' to known clients 24/7.
You mention your requirement ... thin/fat/fair/dark/young/old/bj/bengali/marathi ....
He'll show you a few pics of those available at the moment and the charges
You wait for around 30 min.
Around 3 of them are paraded in front of you
You choose and go ahead.
Suppose you don't like any, pay them 100 for auto fare and go to the next lodge.
If you become regular, the guy will message you when a chick matching your specs is available.
Or if there is naya maal
But keep in mind that these chicks are not as good looking as the DB/OB stuff
Although, they usually make that up with better services and less nakhras
Besides, they are cheaper
Some joints charge around 2.5k all inclusive.
If you're lucky, you may find a gem, believe me.
Happy mongering
