So what did they think they were agreeing to when the driver explained the different routes? As you say, trying to piece together the whole story is impossible. But there's no doubt if they came on toll roads, they should have paid the tolls, if that's what they agreed to, and she should have collected the money at each toll. They slipped away, and she's presumably left out of pocket. Google translate doesn't always work. But she felt aggrieved enough to wait for the police. If it was a scam, and she never actually came on the toll road, would she have bothered? If that was the case, well then she's got no sympathy from me.
