Waste of money hai bhai. And unnecessary headache hai. Plus if you are the possessive type, then din raat ka tension rahega.
But if you are cool and can handle it without getting emotional then monthly salary will be around one lakh in Rajmahal. Some girls can come for as low as 60k too! But then, there will be additional demands for clothes, jewellery, tickets for her khandan, money for some sick relatives, etc. Total upwards of 15 lakhs a year. (OB girls in good bars milk there regulars with astronomical figures. One girl from Cabana OB recently got a gift of Merecedes Umatic.....utne paise mein koi heroine ko baja sakte hain
)
Overall my recommendation is to totally AVOID
