What is the difference between a hotel business center clerk and a housekeeping center clerk?

The clerks in the business center help guests send faxes, surf the Internet, make copies, etc., just like the clerks in the company do.

The clerk in the housekeeping center is responsible for handling the guests' matters in the room, such as what the guest wants to order in the guest room, or the room needs to be cleaned in the guest room, etc. Just by telling you that you have to help the customer handle it.
