bar trolleys tend to be equipped with drawers rather than trays.
each drawer is of sufficient depth for the storage of the different types of item stored in it miniature, half or full-size bottles of spirit, wine bottles, beer bottles, cans of soft drink, and glassware of all types.
most bar trolleys must be packed in the secure bonded store, as the trolleys will have a mix of duty-free alcohol and other items in them.
