this. I bought a Groupon once for a small restaurant and among about 12 customers there was just a single one who ordered conventionally. The restaurant was at capacity and was really small but they sold around 8000 Groupons and when I visited a couple months have passed and it was still completely full with Grouponers. Even though it was cheap as hell (18 EUR all you can eat tapas for 2 people) I won't go back there because the food made me sick.
