"Buy two, a third gift" - a sign on the market near one of the fish vendors. Interested, I approached - the kilogram fresh saucers were sold, the price of 180 rubles per kilogram, not far, meters in ten, the same saucer of 120 rubles, but to the first seller was a turn and everyone took two fish for two kilos, joyfully receiving the same third "shallow", and to the second seller buyers rarely approached, but there were - some feared the high price of the first seller.
I watched further - the trade was boycotted, it turned out, the second seller had time to unnoticed the fish to the first, working for a couple, I understood. I approached and told the second seller that I had unraveled their trick. He did not repel: "You understand, man, when we both stand with a judgment of 120 rubles - almost nobody takes it, then they are small, then small, and we need to sell faster, go home so far! Let me let you go for a hundred.”
