Will also be useful to keep track of who are good tippers. Also with the little video kiosk things they have at the tables, you can serve them targeted ads. Also, keep track of who they are drinking with, this information is worth good money to someone. Also even if they are polite and never cause problems but drink frequently that's helpful information regarding health risks for setting car and health insurance premiums. As well as evidence to police after a fender bender, will definitely want law enforcement to have access to this info. And maybe they checked a box when applying for life insurance saying they didn't drink, but this proves they did - policy is rescinded after filing the claim. Big savings there. Back to that tipping information, maybe they tip people of certain genders and ethnicities higher than others. This could be useful to prove bias in a discrimination lawsuit if they have hiring authority. Few parties dealing with people in any capacity wouldn't want to pay something for access to this really great database.
