"Oh," she said, "What conventions have you run?"
I replied, "Well, I co-chaired the Worldcon in San Jose three years ago."
She brightened considerably, "Oh, thank you so much! I had a great time there! Worldcons are so cool!"
I thanked her, and asked if she was going to be in Anaheim next year, and she said yes, enthusiastically.
That moment was worth at least as much as winning the poker tournament. Probably more so.
