Even he mentions that the shop is not liable if they ask for ID.

Anyway, it’s really twisted my original point your leaning into alcohol laws that do not apply.

If I make a service that says nobody named Bob can use it, have a checkbox Not Bob? - how can I get sued by someone named Bob?

Only if they ask for ID, check it, and it looks so good no one could tell it was fake. That’s about as far from checkbox in a random website pop up as we can get though, right?

In your new example:

- is there a regulatory reason that it is illegal for them to serve someone named Bob? Or is there a real risk/harm that people named Bob would suffer that they know about and is predictable?

- did they do any of the checks they are legally required to do to prevent someone named Bob from accessing the service and therefore suffering that injury? Or make a good faith effort to not just injure any Bob’s, at a minimum?

If they didn’t, then yet a Bob could sue if he managed to get through and get injured.

Pretty weird example though.
