Firstly I'd say it's easy to become addicted. So be prepared for this, make sure you can financially cope with the addiction.
First few pints, go 30 minutes, ideally British girls, but usually Thai,s are very hospitable.
Pay cash. Only take the correct fee. Get a different phone. Keep it hidden. Don't store numbers.
Park away from the venue. Keep a eye on parking issues / sppe limits. Be aware of your safety. If it feels wrong then walk.
It can still be dangerous, you put yourself in a vulnerable place, naked with a stranger. Be vigilant. Brothel's are probably the best for safety, unless Police raided it while you are in bed but unlikely.
Read her reviews. . the more reviews she has, the safer you are.
