Ok, branch manager's time...
Our footfall has not decreased since Internet Banking came out - simple as that. People still want to withdraw large sums of money - car purchase froma private bidder for example. No one in their right mind would release a £6k car without the cash in their hand and you woudn't wire the money to their account until you'd a) seen it and b) had the keys in your hand.
Automation works well, but only goes so far. It can follow a set of instructions whereas a person can go further than this. You say an internet transfer that's gone wrong is easy to trace? Yup. Easy to get back...not particularly. Cheques cannot be phased out either, we process aorund 800 a day through our branch and we ain't a massive branch by any stretch of the imagination.
In summary, internet is useful and all that, but replacing the branch? Not going to happen in our lifetimes.
Money is very emotive and a lot of people simply want a person to deal with it,
