Never make the mistake of asking random people about how to call girls in Noida. It would be assumed that you are about to hire one and this can become news. It is better that you contact the girls or agencies directly via the details available online. If you have a friend who hires escorts, you can ask him for reference only if you are sure that he will not speak about it to anybody. You should also never call the girls or agencies when in public places. Other people may overhear you conversation and they may know of your intent and the news can spread. Talk to them when you have total privacy. Not only that, when you are in a public place with the girl, do not talk about anything that may sound like you have hired the girl. It must appear that you already know the girl and are on a date together. You can also be like a couple with nothing else going on.
