The ideal way it should work is you find a reputable lady with a good website or at least an add telly you what the rate. Place it in an unsealed envelope and put it in your pocket with nothing else other than a pay per use or throw away phone and a condom or two. When you arrive you should be greeted politely or possibly passionately. Sometime within the first minute or two lay the envelope on a night stand, tv, dresser etc and it should never be spoken of. Let her see you lay it down and she may or may not acknowledge it. It might be good to ask to use the bathroom and wash at least your hands. That gives her a chance to verify the donation and it might disappear but should not need to discussed.
