Thank you!im new to the scene too technically. ive only done this a handful of times in the past couple years. from what i experienced, ive always called and booked for a specific girl but u can walk in and request her if youd like. and then shell bring you into the room and ask how long. once you tell her however long you want, just pull out all your cash and thatll basically tell her you want more without directly telling her. then once she sees the cash you can tell her u want this and that etc. hope this helps
