When I've just arrived to Dheli at 03:00 am and exit the airport gate about 4 guys ran to me and said that they can take me to the city center for 50 rupees(about 60 cents). I said no thanks, I have a friend who will pick me up( although it was a lie, but it's better to say like that). I went straight to the metro and one guy followed me repeating that he can lift me to the center. And the funniest part is that the metro works from 06:00 am and I just sat on the floor at the station for 3 hours with a guy, who keeps repeating that he can lift me to the city centre.
