Task: Malevolent Problems
Come up with an original and creative way to react to the following unfair scenario and get back at or sabotage the wrongdoer:
You eat out at a new restaurant in town. The place is nearly empty. The food is fine but not great, and the service is slow (although apologetic). The manager comes out at the end of your meal with a free dessert, thanks you for coming, and asks what you thought of the meal. You do not want to hurt his feelings and believe that with time, they will improve naturally.

Response: Say it was great and thank them but leave a constructive yelp review from a fake or anonymous account
