The restaurant is collecting the data ON the license and correlating it with your drinking habits.
They also use the ID as a subterfuge to collect the info for marketing.
walking into a restaurant is not consent to be a target for junk mail.

Unless he was wanting to pay with cash, then it’s just a silly argument.
It’s kind of like going to the grocery store with one of the “club” cards that you use for discounts. Those things track everything you buy so the grocery store knows how things are selling. Well, if the grocery store asked for a driver’s license when you buy liquor, it doesn’t really matter because they already have all the information.
