You can wait for a convoy for days, they have 1 car, the staff laugh in your face and are rude. It is not possible to find someone responsible for anything. although customs refers specifically to them. After all, the customs founder is, in fact, affiliated persons, for which private traders would have been imprisoned with confiscation long ago.
You need to write out a pass in one building, there is even nowhere to stay normally, check-in in another building, but in order to go there you need to make a lap of honor. I would like to have a pass issued directly at the entrance.
If the shift is good, no problem at all. The paperwork takes from 3 to 5 minutes in each window. But if you couldn't get to the normal shift, write it is gone....
