Who says you're not crazy?
But seriously, I'm glad you posted this. It's sort of like a Public Service Announcement, and could be really helpful to anyone new to the CET program. We may not play for comps, but we sure do like to get the best possible value for our play, and that includes understanding as much as possible about any program you give much play to.
FWIW, I also understand saving up points for something special, as I do that as well. Based on what the host said, I would also have expected her to take care of that meal, but having heard of this happening before it would not have surprised me to have the points used. Like you said, Lesson Learned.
