Rickshaw walas of IIT

Only two rickshaws were permitted to operate in the IIT Delhi campus. I never rode on them because paying as much as Rs 3-5 for going from one place in the campus to another seemed a lot to me. But I did ride them once. That one day in my fourth year, I took a rickshaw to go from the insti to the kailash gate (kailash gate was the exit from the campus to the Aurobindo marg). I took the rickshaw because my sister was getting married and our entire family from different parts of India had come. Because of the proximity of my campus from my sister's house, I many a times used to sneek out of some ceremonies and marriage preparations to attend classes (although I did skip many). Well, all that is quite extraneous. I have a habit of writing a lot of extraneous stuff. Ok, so when the rickshaw wala dropped me at the gate, I asked him 'bhaiya, kitna kama lete ho' (how much you end up earning?). He stated somewhere between 80-120 rupees. I replied 'par bhahar to aur zyada kama sakte ho' (you can earn much more if you operate outside the campus). To which he replied, 'haan, par yahan log tameez se baat karte hain, bhahar koi dhang se baat nahi karta'. For a rikshaw wala a rupee is much more valuable for us engineers. So, he is paying a big price for the dignity he gets in the campus.
