I commented elsewhere about this but it’s entirely dependent on the type of bar and event. That data will be used for holding bartenders who “overserve” liable for someone else’s behavior and there’s so many scenarios where you have no idea who has drank the correct amount.

Imagine working an event — a concert or wedding or anything like that — and some jackass manages to get too drunk. That should be on them but America is the most litigious society on Earth. There’s no way the bar and bartender won’t ever be sued and this data subpoenaed.
