Is there a civil legal relationship between security and take-out?

Does not exist. The takeaway was stolen, and the takeaway staff had nothing to do with the security. If there is social connection, there is no civil legal relationship. The "security" obligation of the property company belongs to the preventive nature, and its responsibilities are limited to the preventive security work in the public areas of the property community. The purpose is to maintain the order of the public area of the property community and create a safe living environment for the owners, which is essentially different from the public security organs to maintain social order and protect the legitimate rights and interests of citizens.
