I think the coffee owner let her business down by not running some projections through excel. "What is the financial state of the business if 100, 200, 500, 1000 groupons sell" But I'm surprised that Groupon wants to take 100% of the payment if less than $10, with no way for the local business to set an upper-cap. A good parasite doesn't destroy it's host, a bad parasite does. To expect a small business to sell $13 worth of retail-priced product for $0 seems like a bad parasite to me. Also this from the blog posts comments is quite a gem: "what could I expect from the only establishment in Portland without a drive through window that is using crisco and kraft “mayonnaise” while claiming to be kid friendly." OOH SNAP!
