Speakeasy
Can I move a barrel from my Stills to an Operating building in the same district without a Truck?
No. Every delivery needs a Pick Up and Deliver action (Garage, a Fleet card or a City tile); there is no free transfer, even inside one district. Barrels also cannot be sold from a Truck: they must be delivered to an Operating building first, and a Sell action does not unload a Truck.
