My grandfather was born in 1909 and worked for a long time, up to the age of 76. For 60 years, he received in service a gift of expensive (300 rubles) and a deficient novelty - a radio on his legs, they only started to produce them.
After a while, I had to bring the radio to the home to repair.
Having seen such a rare inexpensive thing, there gladly counted for repair more than 10 rubles (you understand, a considerable amount of money in 1969). Grandfather paid for it. The next morning he was called, long apologized for the mistake and that the amount is about 3 rubles.
The grandfather thought and decided that the price was reduced when they read the engraved gift plaque on the radio: "That's for good faith work on the day of the 60th anniversary. Signature of the Prosecutor General of the USSR
by R. A. Rudenko.
(My grandfather served in the prosecutor’s office for 40 years.)
