Drivers tend to be aggressive, so drive carefully. Pedestrians should be especially careful. Petrol is purchased by indicating the monetary amount for the quantity of petrol. For example, one might ask the attendant for 200 rupees of petrol. A sign on the pump should indicate the number of liters that specific amounts of rupees will purchase.
Prices are fairly consistent between various pumps.
Watch the meter on the pump to make sure it starts at zero and ends at the amount requested. The attendant does not expect a tip. This happens at petrol pumps and also when cars stop at intersections. Drivers who want the windscreen cleaned should tip the person 1-2 rupees. One will also find a variety of hawkers at intersections selling goods such as flowers and newspapers.
