Zatarivatsya at the Crossroads. The cashier says to you 14,361 rubles begins to check it finds an error, "Oh, for some reason, corn made its way over 9999 rubles, sorry, will correct right now." Th-there reigns amount becomes 4362 rubles, sorry, sorry, all right, I'm going.
But the four-something gnawing inside. Checking the check again - 2 cheese Chechel punched 1278 rubles! At 639 rubles apiece!
I come back to the store - oops, mistake, oops, sorry, we will refund the money. The money was returned and asked to send a check! There is already no doubt left that tried naipat.
The essence of the layout seems to be an obvious mistake to distract the buyer and the quiet steamed him by excess Tyshchenko. Buyer relaxes - hurray, an error is found and corrected, and no longer checks the check.
In general, keep an eye, you can not trust anyone!
That check:
