I wound up in line behind her again at the small bar, and I took the opportunity to compliment her on her choice of accessories. Not shockingly, she too was from the Bay Area (the con was in Reno, NV), and she was a part-time professional dominatrix. She gave me a URL for her dungeon's site, which contains some decidedly non-worksafe photographs of her, um, work.
We had a nice conversation back at the tables a bit later which gave me some chances to embarrass my lovely companion (the girlfriend, not the pro-dom). Vengeance has been promised me at an undisclosed date in the future.
I meet the greatest people.
