Can guests sign an exemption agreement when packaging unfinished ingredients?

1. The customer packaging exemption agreement is invalid. As an operator, it is an obligation to ensure the safety and reliability of food. If there is something wrong with the quality of the food itself, we can't shirk our responsibility because of this agreement.

2. When the customer goes to the hotel for dinner, the service contract relationship between the two parties has been formed. After consumption, the customer still has the right to control the leftovers and the right to package the leftovers.
