If you can find lots of new Scottish talent I am sure the sauna owners will pay a kings ransom for the secret.
The decline in Scottish sauna talent started about 15 years ago. My first sauna punt was around 1994. I had seen the various signs outside the buildings but never ventured in, then there was a big news story when LSS had graffiti of a particular nature sprayed on it. The newspapers picked over the details of the sex for sale saunas and I decided to visit said LSS.
From 1994 to 2012 I visited BSS, LSS, even NTS (it had serious talent late 1990s) and even Scorpio before it started its long decline around 1999/2000.
Pre-2002/3 Scottish talent was everywhere, even NTS had stunning young Scottish girls. Carol, who probably had the best body of any sauna girl, worked there.
Then a few shops started selling mobile phones to the masses and the internet became widely available and the rest is history.
My first punt though was not in a sauna. Who remembers the carpet shop in the West End that wasn't only a carpet shop? Anyone? Through the back and ask for UNDERLAY. Was so embarrassed could not get hard or even close to excited. Remember thinking afterwards "masterbation was never this difficult".
