Service-oriented businesses tend to have positive experiences. Pretty much anything where you may have somebody sitting around 1/2 their time doing nothing, just to make sure you've got coverage during all of business hours. Any money you recoup from that 1/2 of the time is money in your pocket. Anything with inventory costs (e.g. restaurants) have a much harder time. Food costs are a significant portion of the cost of serving a table. It wouldn't be bad to have a loss-leader for one or two meals, but grouponers don't become "the next repeat customer", so you just lose money on the meals with not much to show.
