I feel a reminder is warranted, especially for any newbies out there: NEVER, EVER PAY A DEPOSIT OR PAY UPFRONT PRIOR TO SESSION. One of our own has made this error recently and it deserves a reminder.
Providers: Please do not ask for a deposit or payment prior to session. I know there are creep customers who try to take advantage, or are no-shows and waste your time. The same can be said for some of you, although the vast majority I've encountered have been fair and forthright. We can all succeed in what we want both as a client and as a provider; just both sides play fair, be nice, hygenic and most of all have fun!
