They sat down, and while eating they noticed that in a flow of men coming in and going out in remarkably similar black clothing. Two, four, then a few more of them came in, and then grabbed four men eating at a neighboring table, dragged them into the street, loaded in a van and took them away.
Here, my friends, what happens when you eat khinkali in such turbulent times. Be careful not to enter a restaurant without an urgent necessity.
