Riho:
Sometimes it is easier to pay, not to spend 3 days on the border waiting for them to put a stamp in the paperwork.
Thats true.
But paying is not the only option.
I was through this years ago on Bulgarian-Turkish and Bulgarian-Serbian borders. We came up with idea wchich turned out to work perfectly:
They were suggesting that we might be there for long and there is a way to speed the things up. I made it very clear that I can wait even 3 days. We demonstratively slowly unloaded half of our car and set up a small picnic site on the side of the road. So they saw that no chance for bribe, so at least they wanted to spite us and gived all our documents back to us and told us to move immediately. Off course, we were prepared to pack up in 15 secs so we went trough before they had changed their mind
It worked three times (at the fourth times we came to the border just after some Polish TV lorry and they were just bargaining on how much they will have to pay and when they saw us they said “OK, we pay that, but the Polish kids are going as well” and Bulgarians agreed to the deal. So I used the bribe, but I did not paid it myself
The “picnic” is one of the thousands of ways to evade paying bribe. But the basic point is:
If they feel that they can break you and that you will pay (if not this time, the next time you will be there) they will keep you three days. If they feel that you might be waiting there till the next coming of jesus christ and dont pay them, they won’t keep you, as you are only annoying them.
And as I said before there is no point to ask for a bribe from an english driver because of the language barier, so they just let them go.
Oh, believe me, it’s very easy to say. I was asked for a bribe by Hungarian policeman and by Turkish one and they were VERY clear what they expect. I managed to let them know VERY CLEAR that I would rather prefere to pay regular ticket, and on BOTH occasions I was let to go my way without need to pay neither the bribe, nor the ticket.
But I really doubt that your friends have not paid on the border.
Lucky for them, your doubts has as much influence on the reality as your guarantees
