Nosh restaurant at HK airport

I compliant finally :
1. Type and record the wrong check in or food delivery time to avoid challenge
2. Not to deliver food by the sequence of order or tickets
3. For a microwave heater instance food , they ignore the service procedure
4. When raises my concern , the trainee asks cooker to hear my sandwich , it take less than 30 seconds
So this is why I complain to the store manager
