I worked in a network of famous supermarkets (I will not name the name) and over the box there is a camera on which everything is recorded, for every time the cashier issued alcohol without asking for a passport he was fined. (the first time for 100 rubles, the second for 200 and so on). So gentlemen, you are not especially happy that you and your chatty and 3 grandchildren did not give 18 :)
