or

Don't eat food inside.

Based on the given information, the correct sentence to use as a stop sign, in the context where there is a drink and a sandwich, would be:

"Don't bring/use food and drinks."

To determine the correct sentence, you followed a set of instructions or rules provided (i.e., a list of things that are not allowed). In this case, you identified the sentence that corresponds to the requirements of not bringing or using a specific item.

When encountering a list of rules or instructions, you can analyze each point individually and apply the instructions accordingly.
