Just go with your gut instinct should be fine unless you really dont have much experience with girls in general. Some up coming young thing are actually worth a bit of money and have a bright future looking to get a head start thats the reason they do the job and earning more than 100K tax free and the good one will be around 200+
and hope they put that money for their future as it will be sad to be still servicing old man till they reach 30s thats just sad.
Just look at their hygiene you should be fine if your not sure dont do anything that you might regret. Most season WL are quit clean and know how to look after them self as they need it as their income you will hear their name mention like 5* or one girl you hear about from 127 go with many review is the safe bet ( shit I forgot her name already )
