I run several business. One is a restaurant. In the past year, we have received some bad reviews on the internet. While many of them are from vendetta driven fired employees, when the bad reviews are real reviews, meaning from genuine customers, I am actually quite happy.
Why would getting a one, two or three star review make me happy? Because knowing enables change. So many times in life you think things are great, because you choose not to look at them -- or you are too busy to see them. Unhappy clients force you to re-evaluate who you are, where you are going, and who you want to become! I embrace every bad review as good. That's the key to positive evolution. Our restaurant business has improved because we listened and acted on the bad reviews. We have even gone so far to ask people who have given us bad reviews for clarification and suggestions on how to make things better. Their feedback has been fabulous and productive.
So embrace bad reviews, learn from them, and utilize them to your advantage!
