It's true that things were better a couple of years ago, if you are partial to a touring Polish girl, which I am. The Romanians have helped put an end to them on way or another which leaves mainly Romanians (tried a couple and decided not to bother any more) and English girls who work sporadically and seem to be a pain in the arse to make bookings with.
Put another way, a couple of years ago when I was looking to punt I would typically have a choice of 6 girls, now it's far less and now and again I come to the conclusion that I should leave it and look again in a week or so.
Ironically the Romanians I've seen have all moaned on about how slow business is, whereas the Polish seemed to have all the punters they wanted. Perhaps the Romanians will bugger off and stop dominating the touring scene - here's hoping.
Edit- there are punts to be had but they are harder to find now.
