2 words: REPEAT BUSINESS. Money in the bank. And the smart ones understand that. They know you have other options.
Nah, it just means you're forgettable and not worth remembering. MY regulars remember me, even if there's been a gap of almost a year since my visit. And it's not because I tip. It's because when I am BOTG, I visit regularly, paying standard rates. Just last week, I remembered to ask a PRC where I could find a certain snack after our session. She told me to wait and left the room before I'd paid her. I finished dressing, she hadn't returned, so I went out to the lobby to look for her so I could at least pay her, given I'd already stiffed her. Just as another provider asked if she could help, my regular returned, now changed from work clothes to civies. Took me out of the shop, stopping to ask several shops where the snack could be found, taking me by the hand when crossing streets (felt like a little kid). Found a shop where the snack could be found, and she ordered for me, and not just for me, but also for the friends I was meeting after, plus some additional items she suggested. AND she insisted on paying for EVERYTHING which was more than a pineapple... I know because she handed me the receipt as she had to get back to work and it would take time to cook... AND that was my last visit with her before my summer hiatus. So it is YOU.
