I've been watching the competition lately and noticing their Groupon custys leaving bad reviews on Yelp, they mention their "Groupon special, LOL" shiteatinggrin Looks like one slip up with these types of customers and they will BBQ you on another website which is all about reviews. Some may do okay with Groupon at the moment, but it can leave a long lasting scar on Yelp or Google if something goes wrong. In fairness to the competition, it's been about scheduling issues, not the work. But bad reviews are bad reviews.
