People appreciate the facility to leave their coats, bags, briefcases and other items for safekeeping while they enjoy the lunch, cocktail party, dinner dance, conference, or whatever the event is.
With a large gathering of people, the rows of hooks and shelves behind you in the cloakroom will soon get filled. You may also provide certain luxurious personal touches in a hotel: filling a wash hand basin with warm water, so it is ready for the guest to wash his or her hands, a clean towel placed nearby.
When queues form, as inevitably happens when everyone wants to leave at the same time, you must maintain your calmness and friendly, yet efficient service. You must follow the labelling and storage system accurately and knowledgeably, so that you know immediately from the ticket where to find the items and reduce the risk of handing over property which is not in fact the ticket holder's, but someone else.
As you are one of the first and last members of the team the customer has contact with, good customer care skills are very important.
