I have a acquaintance. A smart man in his years. He lives in the Krasnodar region, and previously often travelled to relatives in Osetia, it seems. In those years, the 90s, the trips were quite problematic due to the greedy Caucasian and Krasnodar Haishnikovs. Often stopped and shaken. My uncle, not knowing the psychology of the servants, used this trick to avoid bribes:

- he placed in the load pocket a package of a wallet, a driver's license and red crustaceans of a la ment or gbschnik.

And here, when he was required to present the documents, he got the whole package, scratched the driver's license from it, and the rest as if unwittingly transferred to another pocket. An interested haishnik, attracted by bright (possibly dangerous) crusts, necessarily asked suggestive questions about his uncle's profession or crusts. To which the uncle replied with the crown phrase:

No, no, it does not matter! I am a simple citizen today.

It always worked ?
