So... you need some fuel for the rocket powdered drill, huh? When Emmett asks you to complete some tasks in exchange for the drill, you'll want to head on over to the soup kitchen.
This can be tricky. Eat some soup a couple of times telling Cue Ball to add ingredients. Try the side kitchen door by the phone while Cue Ball is busy. Then talk to Emmett about how to prop the door open. Eventually the door is propped open. Leave the kitchen and come back, walking towards the phone. A scene will trigger showing how the booze is lowered and delivered.
Taste the soup. When he moves the rack, tap on pipe. Watch scene and then leave. Talk to Edna and tell her to deliver the soup to the Sobriety meeting. After arguing with Emmett and another scene, the achievement should unlock.
* SPECIAL NOTE* When I left, I went to talk to Kid and *SPOILER ALERT* stole my grandfather's hat back. I'm not sure if this is necessary but that's how I roll!
