The post office is open 2 days a week, correspondence is not delivered. The head of the communications department is paid little, but you need to work for 4. That's why the locals don't want to work there. They send visitors.
So that the mail works more, not twice a week, and even the schedule is from 10:00 to 16:00, if you don't come, the queue is all the time, it's generally bad
