Hmm........
This sounds interesting. The idea itself is good, but the lines at BGA (at least when I'm there) aren't very bad, about 15-30 minutes for the coasters. I'll have to see how it goes next time I'm there... because I don't find it necessary. Nice addition, but I probably won't use it alot. And like Barry said, I would use that on food and other things, not the QQ.
