I understand what you mean but in my case and other girls I have toured with that wasn't the case and even when you put hygiene in the saafe bar there are so many ladies reporting how dirty clients are and it is alot.
I was in London , Edinburgh, Bristol , Ireland , Manchester ( Asian guys were very clean but i was getting lots of guys my age and most are into their appearance , the local guys some were not clean at all) .
But it is well known Nordic people are very well dressed and their hygiene follows but yes in London even charging over 350 an hour the clients were not so clean , of course i had some that were , but the rest were not , Ireland had the dirtiest and many discussions from so many girls, only reason i went there the Irish are super nice and if new you make lots but uk didn't fare better in terms of hygiene.
Just my opinion and others i have met , talked to etc
