Next time when you are caught by traffic police, pay cash and do not ask for receipt

Ok. First thing. Keep all documents proper with you while driving the vehicle. Docs like License, Pollution check, Insurance etc. In spite of having all proper documentation, you may be stopped by traffic police and ask for money either you violated the traffic rules or something else. What I feel is ....just pay the cash and do not get receipt. You may wonder why?
if you pay cash and do not get receipt, it is for Police person to get it.
Just imagine, what will happen to the money you paid and get receipt. it will go to government. then you know what will happen to that money....starting from 2G to anywhere.....
