this is my advice, don't take other peoples words for granted, because everyone is different and their chemistry and reaction is not always the same,
a girls regular might get better service, than a first timer off the street, unless you are young and hansom and the girls type, than you might get the best sex ever,
in saying so just go to the shop when they open meet the girls in person and see if there is any chemistry, watch the girls eyes and body language if its lit up choose her, if she looks like she is not interested don't pick her it could be the worst punt ever, even if she's got good reviews from others.
