Ivan Nevsky wrote a comment that sellers are not one-dimensional.
There is no such word .That's why it seems to him that buyers are submitted by sellers .I constantly shop in "Lana ", I did not notice rudeness in my address, but rather on the contrary, sellers served customers.Especially the seller Zoya, who is always polite to customers and their grilled chickens are delicious.
I've read all the comments.And I would like to conclude by saying that
there is a book by Irina Neuman "The Law of energy exchange".
