Final answer:
The exact warming time for an in-Restaurant sales packaged cookie is not provided in the information given. Specific warming times would be based on a restaurant's own food safety guidelines.
Step-by-step explanation:
For in-Restaurant sales, the minimum warming time for an individually packaged cookie is not explicitly mentioned in the materials provided. Food safety guidelines specify that perishable foods should not be left at temperatures between 4 and 60 degrees C for more than two hours, but this does not directly relate to the warming time for cookies. Additional information or context from the restaurant's own food handling procedures would be necessary to give a precise answer. A best practice for restaurants would be to follow the guidelines established by their food safety program, which should be based on ensuring the quality and safety of the food served.
