So I did it, in fact twice now. Entered xxxE, knowing fully well that fare to my destination was Rs 6. Took out two 2 rupee coins - no ticket given, no questions asked. Next, I tried this in a Volvo xxxC. Was a bit nervous doing it, and must tell you that I succeeded only in my third attempt at this. Entered the bus, and when conductor passed by asking for tickets, I ignored him.
