You have to be a local or an expert haggler to survive in Varanasi. If not, a rickshaw-wallah will sell you right there, on the street as you stand, to another rickshaw-wallah! Almost all tourists have to go through sometime torturous and unending offers of all kinds from touts, wannabe guides and rickshaw/autowallahs. Those offers include shaking hands with them, to let them massage you right on the busy ghats, to tip them for nothing significant and to go with them around the city. The moment they realize you are not from the city, they are after you.
