Travelling through Europe with my then boyfriend, now ex-husband in the mid 1970s.
Expensive car - Jaguar - with GB plates loaded with our all our stuff for the journey.
We were in Bulgaria on a completely deserted open road when from seemingly nowhere 2 men dressed in slightly tatty looking camouflage fatigues suddenly leaped from the side of the road with their hands raised for us to stop.
They claimed, in broken English, that we were speeding, we possibly were, the speed limit was ridiculously low, and demanded we paid a speeding fine in Leva (local currency) but we really didn't have much Bulgarian money as you were only allowed to change your currency for a very small amount of Lev while you were there.
My bf, who was a stubborn arse refused, claimed we weren't speeding, at which one of the men waved his hand vaguely in the air and said radar.
It was at this point I noticed that they were each carrying some sort of submachine gun.
Bf sad we had no Lev and so they demanded we pay the fine in American dollars or Deutschmarks or ££s and so on through various European currencies.
All the time I'm telling my bf to just pay the fine and lets be off and all the time he's arguing with them and telling them we had no money on us. And all the time they're waving these bloody great guns around.
He wouldn't give in though, and in the end they got bored with us and sent us on our way.
Have no idea who the hell they were, they could have been some sort of police, militia or just a couple of blokes trying to make a bit of spare cash, but it was bloody scary.
