In Las Vegas, they have plumbing for booze.

Basically it's more practical to keep the booze in the back of the casino and plumb it into a network of bars, instead of keeping track of which bar is running out.

Particularly when a single casino may have a hundred bars.

Most places keep the kegs in a centralised location and pipe it around, whatever the size. I'd be surprised if the US were much different.

You don't want delivery men rolling barrels around hotels etc, and you want to keep the beer cool. Plus bar space tends to be at a premium.

They have beer pipes in Belgium, too.

From a brewery in the historical center of Bruges to the outskirts IIRC. Which allows a working business better transport links so it can stay in the center to help avoid the city becoming completely Disneyland.
