Agreed. There are also a lot of ladies who will never give an HE or any sort of naughty pleasure but are very aware that guys will tip more and come back often if they think there may be more to offer in the future.
How many of us returned to Gloria at least once back in the day with this thought in mind? Kali downtown is another who is expert at giving the impression there could be more in the future, even though I'm pretty certain after several visits, decent tips and a great rapport that it's not gonna happen from her.
