Will have to wait to see the details but I don't much like the sound of having to register and check in to go to the pub. What happens? How does it work?
Say the stedded-up chimp on the door takes your details. What does he do with them? Where does that list go at the end of the night? Chimp decides actually, I don't like you because or your colour, gender, sexual orientation or because you manage to annoy them somehow. Let's face it, it ain't difficult to annoy doormen, is it? Or maybe he thinks you're on your own, very drunk and therefore vulnerable and decides to let his mates know they can break into your house, 'cos you're in the pub. Or perhaps steal your identity, Maybe beat you up on your way home or rape you. I hope some serious thought into how something like this will work has been done, but judging by previous form, I doubt it. Guess we'll see.
