I almost always do incalls, occasionally I host at a hotel. At a hotel, I always leave the cash out in sight. Incalls are interesting. I have the cash ready in my pocket and I have a tip ready, separate from the payment, but then we usually get into it pretty quickly after I arrive, so I forget about putting the cash out. When we're wrapping up, I leave it out in plain sight. One of my quirks is that I don't like to just leave the cash by the bed. I like to leave it someplace nice. So if there's a desk or a nice plate on a dresser where he leaves his change and his keys, I leave it there. Its never been a problem. I have, on occasion, handed him the cash directly, but its weird, so I would rather not.
