hello, contracted canteen, not belonging to the collective dining distribution unit.

the collective dining distribution unit refers to the unit that processes and distributes food centrally according to the ordering requirements of the collective service object, but does not provide dining places.

For example, there is no canteen in this company. After your company has processed the food in its own processing place, it will send the food to the company and provide tableware to distribute the food to the diners. Then this kind of business behavior of your company can be regarded as a "collective dining distribution unit".
