I usually do my research, make a selection, and book. A while back, I was unfortunately stood up at a spa, so decided to go the lineup route to choose a girl. Very educational as I ruled out several that on-line presence didn't immediately rule out.
I would say that since the OP booked the girl and there wasn’t a bait and switch, but rather a lapse of ability to keep tabs on the OPs extensive hobby list, tipping is the classy thing to do. Now if it wasn’t as advertised then I see no reason to tip. An apology and about turn would do. Unless you make a habit of bailing, you are not going to get banned.
