It was in K&B. Two absolutely strangers buy alcohol, one in the mask, the other is not. And the strange thing is that it turns out that you can walk around the store without a mask, and nothing can be bought at the box office! The one in the mask paid for the purchase, and the other the cashier does not sell! The final - the first removes the mask from the face and transmits and says, "Keep Brother, you need it!" The second puts on a mask, buys a bucket and leaves.
