Police raided the restaurant 66 Hot Pot in Mong Kok on October 15, and found that two customers gave the wrong phone numbers when registering their personal information on a paper form.

Another diner was found not having registered any personal information nor using the LeaveHomeSafe app at all. Cheung Chun-kit, the 42-year-old operator of the restaurant, was arrested by police following the raid.

He appeared in West Kowloon Magistrates' Courts on Wednesday and pleaded guilty to failing to comply with the instructions under the Prevention and Control of Disease (Requirements and Directions) (Business and Premises) Regulation.

He had earlier admitted his own negligence under police caution. Judge Veronica Heung Shuk-han fined Cheung HK$8,000 for his offense.

In mitigation, the defense said the nature of the case was not serious as it only involved three customers.

The lawyer added that Cheung has learned a valuable lesson and has arranged workers to “stand guard” at the front door to make sure all diners comply with the requirements.
