I'm surprised no one mentioned 3rd party audience lists. It's more than likely in this case you used your credit card at the restaurant and this data was passed to a data service like DLX or Neustar, which Campari will pay a fee to get audience lists such as: Datalogix » DLX CPG » Alcohol Beverage Buyers » Spirits or AdAdvisor Audiences powered by Neustar » AdAdvisor Consumer Audiences » Alcohol (Restricted to Best Practices) » Consumption Location » Liquor-Where Consumed-Restaurant As to why Campari specifically, that could just be a coincidence. Have you seen other alcohol ads lately?
