Resting a mixture and storing food are different questions
The idea
A recipe may include time for flavors or textures to develop. That instruction does not, by itself, tell you how to store the food safely. The ingredient mix and the conditions still matter. Do not treat a restaurant preparation timeline as a general instruction for your home kitchen.
A practical next step
Use the storage guidance that applies to your actual ingredients and recipe. Ask the restaurant for handling instructions for prepared takeaway food.
