The best part about this is that you don't have to go find someone to get these notes. If you have a printer, you can just print them out yourself, how many ever you may want. I'm a bit sceptical of all the success stories though. I'm going to try this with the local traffic policeman the next time he pulls me up, and check his reaction.
Yeah. Probably the most frequently bribed people in India would be traffic cops on the beat. They confiscate your keys and won't hand them back until you pay them.
