It's good that it's just there. A huge disadvantage is that in order to take an appointment ticket, patients take up a queue a few hours before the clinic opens and stand in the cold acquiring new diseases!
It's just terrible! Doctors don't know their authority, if you don't have a ticket, then die at the door, even if the doctor still has work time left and no one else is in line. You can't find the head of the clinic at the workplace, they can't clearly explain at the reception where their boss is, when they will return, and whether they will return at all! Well, the appearance of the polyclinics itself is a separate topic!
