More than once, the situation has just escalated today.
I go in, say hello, the seller does not greet me, and did not even deign to shake her head in greeting.
Communicating in such a tone as if I had disturbed them in their private home at their private time. All communication with a favor, with a strain, as if not with people, but with a piece of something smelly and unpleasant, the seller needs to talk.
The situation is constant, regardless of who is working.
