A restaurant owner in central China has become an online sensation after tearing up an employee’s IOU (“I owe you”) note for a fire that almost destroyed his business. Liang, 45, a veteran restaurateur from Zhengzhou, Henan province, has spent more than two decades in the catering trade and now runs a barbecue restaurant with over 20 staff. One of them, Liu, a 27-year-old chef who has worked there for seven years, posted a photo of the torn-up note on social media on July 3. The story behind it.
