> The owner or the liquor store I worked at required the drivers to do a lot. Heavy lifting and placing product. They are defacto employees. Owner of a liquor chain has great pull.

It's perishable, so it benefits greatly from more frequent smaller deliveries, instead of rare large deliveries. If you don't have to pay a person to drive, you can do that. Additionally, the packaging is perfectly regular (cans or kegs, always the same size, made of a durable material).
