It all depends on where the girl is.....and sometimes what you think might be a well-earning area isn't.
I know a couple of decent looking Romanians in Blackpool who struggle to pay the rent and rates on their flat each month. You'd think with the supposed party atmosphere in Blackpool they'd be overrun with punters, but in reality they found better business when they were living in the muslim areas of Blackburn. Blackburn has plenty of young asian lads who want to shag a white woman (they can't shag muslim girls without risk of serious reprisals). All Blackpool has is family trips (no potential there) and stag parties who, once they've finished drinking then stagger to the parlours and puke up outside. The girls get a lot of calls from pissheads at 2 or 3 in the morning....but whenever the girls have tried attending one of those it always goes wrong: fake call, locked hotel, punter won't pay, punter is drunk or stoned. And the few punters who do come during the day invariably just want a 15 or 30 minute quickie. There's no money in that.
The girls thought they'd be better off in Blackpool (they didn't like the way the asian lads treated them in Blackburn) but it badly backfired on them as a move.
I'm not suggesting all Romanians are hard up, just pointing out that some of them don't make as much as you'd expect.
