The bus 540 which runs from avadi to chengalpet is one of the 4 busses which passes through vavin and goes through tambaram. And this bus does not stop is most of the bus stops most of the time..and when asked the conductor(who are always very rude) they say if the ystop in all the bus stops it will get very late...and most of the time they make people get down at the signals and never stop at the bus stops..why are there busses plying if they dont even stop at the bus stops? And what is the point in reaching the destinatin on time when the bus has no passengers in it??
