Ok, guys. I might be too naive, but I thought the way it worked was as follows: punter walks in, wg greets him, kiss-kiss etc., wg leads him to her room, asks him what she can bring him to drink, she brings him the drink and ASKS HIM ABOUT WHAT SERVICES HE IS LOOKING FOR (if she hasn't done so via texts/messages before!!!) and money is only handed over once they have agreed on the list of services. If for any reason (be it lack of time, my inability, or the punter's inability) some of the services that had been specifically payed for (definitely in case of extras, but in case of the basic services too) haven't been provided during the session, the minumum I can do is to offer MONEY BACK! If the wg doesn't offer money back, you have every right to ask her to refund you, in my opinion.
