There are companies that audit bartenders by very carefully inventorying the liquor. I found out from this article in my college's newspaper: http://www.michigandaily.com/content/2008-09-24/bar-audits-m... .

The company is Bevinco (www.bevinco.com), and I'm sure there are others.

Yeah, I remember watching a video in an accounting class about internal controls of a bar in Texas which would weigh bottles every night and dispensed drinks through a soda gun.

Found another example of companies using some audits to keep track of liquor usage. [http://findarticles.com/p/articles/mi_m3190/is_43_40/ai_n267...]
