Okay, I'll admit it, I'm a freak. I Love those things!! I don't always buy, but I love looking at the brochures and thinking of what to buy, and I love having a Girl Scout cookie fix every year. As someone who had to sell that crap while in school, I'm happy to help someone else sell it.
I've gotten to the point where I don't buy something if I don't need it, and that's that. Saying no doesn't bother me anymore, so there's no problem. However, I work in a nearly-all-male workplace, so I don't see much of that stuff anymore.
