There was an inevitability about this though. After Brexit, all the European girls decided the UK was not worth the effort. After Covid, a lot of girls found better things to do with their time. With the huge increases in accommodation costs (largely due to stupid government ideas) fewer girls can turn a decent profit. Added to that, parts of Scotland have a bad reputation with girls for time-wasters and no-shows so there are fewer tourers from down South.
It's not going to get any better, but then again this is what those in authority want. They want prostitution driven out of the country. It's just being done by stealth/circumstances rather than overtly.
