I understand but to keep track of something like that in wdw is much harder. And that is the place at hand. Don't you think?
But like another poster already mentioned that those magic bands in the future will be able to track the number of drinks.
Yes, it is difficult (sometimes practically impossible depending on the server's experience, among other factors), but WDW's policy toward any CM serving alcohol is that they have to monitor each Guest. We have to take a refresher test every quarter to show that we know the Florida laws and the Disney rules. If you fail the test, you have to take a class. Failure to cut a Guest off is grounds for termination.
