Bob likes his booze. A lot. He may be a recreational alcoholic, or drinks to escape remembering his Dark and Troubled Past. Fate, being a cruel and fickle mistress, has other ideas. Alice drags Bob (usually shambling and slurring rather than kicking and screaming) somewhere without liquor of any kind. The reasons vary, Alice may be doing an intervention, she may be trying to save his life from people out for his blood, or Bob (all by his lonesome) stumbled onto a bus/ship/plane/rocket/FarsideIsland to a place where the only spirits are of the figurative variety.
