Which of the following is NOT a pre-close task?

Preparing sandwiches is not typically categorized as a pre-close task. Pre-close tasks are generally focused on ensuring that the workspace is ready for the next business day and maintaining cleanliness and order at the end of the operational hours. Cleaning grills helps maintain hygiene and prepares the equipment for the next use, while taking inventory for the next day ensures that staff are aware of stock levels and can make informed decisions for the following day. Stocking items is also essential as it ensures that everything is in place and readily available for service.

On the other hand, preparing sandwiches is more of a task that happens during operating hours when customers are being served. This activity doesn't contribute to the end-of-day preparation procedures, highlighting why it stands out as the correct answer to the question.
