Observing the observed from a bus-stop

Well, as a part of the data collection process, in which the demand during peakhours at bus-stops are to be noted in a form(for the proposed IT corridor along the old Mahabs road from Madhya-kailash to Kelambakkam), it was my turn to go to a bus-stop at Sathyabama 'deemed' university.
We were a group of 5 guys(4 guys actually) and we were each assigned one bus-stop to collect data from. As the peak hour starts around 7 am and the bus-stops were quite far away, we had to start early from the tharamani gate. The auto guy outside asked a ridiculous 150 rupees, his logic being that share auto from tiruvanmiyur charged 20 Rs/guy and since it was early morning time, he had factored in the additional Rs 50. As this was a bigger auto(it had the normal seat pushed a little up and back and an additional wooden seat added just behind the driver's seat), we conceeded.
The form which we were provided with had columns for arrival time, departure time, no. of passengers getting in and out. The only two buses which served my bus-stop were 21H and 19B. 21H was more frequent of the two and had an average frequency of 1 every 10 minutes.
As the auto approached my bus-stop, my friend who was to take care of navallur bus-stop commented that IIT-roorke had come. I didn't understand so I looked out and saw that the building in the distance resembled the main building of iit roorke..Well so much for that.

I was happy that the bus-stop was sheltered and I could have a seat and do my work(which wasn't much anyway). Soon, I got to see the first of the Joseph engg. college buses stream into the road that connected the main road to the university. The univ. buses kept coming..I counted around 10 in 5 minutes. As if that weren't enough, another set of 10 buses arrived barely 5 mins later. This process happened for another 15 minutes...I had lost track of the number of buses that went into that university. My friend mentioned later on that the combined fleet of sathyabama, joseph engg. college and Jeppiar college was around ...hold your breath..70.
Speaking of Jeppiar college buses, these buses slowed down as they approached the bus-stop and enabled me to have a decent view as they passed by.The other private buses I observed were, hindustan engg. college,vmrf college,lots of polaris buses. I also got to see some exotic things like horses being carried around in lorries, a drunk guy asking the guys sitting on a minivan to get down and stopping guys walking around. There were also a group of 4 students who had to go to Kelambakkam(the last bus-stop on 21H and 19B route). They were looking for an auto but couldn't get it..so they approachd the bus-stop. Then suddenly one of the two girls, started waving the finger(both hands!) towards Sathyabama university...quite funny to watch.
I don't understand why this college has to impose restrictions on many things....like - You have to come to the college only by the college bus, even if your house is just a furlong away.
Interaction between boys and girls is strictly prohibited and could lead to expulsion!...I'd say, a healthy interaction is necessary between the oppsite sexes, else we would have a lot of perverts(which is the case mostly). This isn't any school where you would have to worry about students falling for infatuation. The very fact that you have put in the efforts to get into a so called 'deemed' university, show that you are sufficiently motivated to study. What about all-round development of personality..I don't see it happening in such freedom-curtailing , closed environment that they have managed to enforce. On the other hand students would be frustrated and would have given up in life. These things could only happen in chennai..No wonder Chennai is given the tag of a conservative city.
