Be careful!
Duplicate screens for the buyer have not been working at the cash desks for a long time. People have repeatedly made comments. The sellers replied that they would do it soon. But apparently they are just being turned off.
Yesterday I fucked up once again specifically in this penny. I always take a package of groceries. I do not check the receipt, but after several incidents I began to throw it into a bag.
At home, I found a kilo of cookies in the receipt for 9.99 rubles, which I did not take.
