These carriages in cities like Kolkata can be and should be compared to the pirates in the deep blue seas, with their flags flying high, occasionally they join the others of their clan in a cove like gas station. They are the kings of that part of the city like any part of the sea. They may give you a ride or may get you late for your office depending obviously on their mood. To them the most precious of the jewels is the change money. They only listen to those who have change. They like to enjoy in their cove like the pirates (not mentioning the accessories). Like the British Navy the City Police sees them with deep respect. Who knows you may even find a Jack Sparrow if you are lucky
