Beer delivery is a job that involves transporting beer from one place to another. The term 'CASES' is an acronym for the five-letter word meaning 'Containers of Alcoholic Spirits for Export and Sale'. This term is used to describe the containers in which beer is typically transported. Beer delivery workers are responsible for loading, unloading, and delivering beer to customers or other locations. They must also ensure that the beer is stored and handled properly to prevent spoilage or contamination.
