FlyPenny - put Thanks! into your pocket

As a joke they say: "Thank you in your pocket you will not put!". Now, and this is serious, you can say "Thank you!" to any person and thereby give 1 ruble discount. Let the other person feel your attention and get to know you from the best side. One ruble, it would seem, is a trifle, but, making a transaction, the value of human appreciation and respect is fixed.
