Its all in the approach! I personally prefer the human touch but at the same time the self service thingys are the way of the future whether we like it or not. The big problem is with human nature, people dont like trying new things so if we are to get people to use the machines we will literally have to force them into trying it. Eventually the customer will realise the benefits and wont be afraid of it anymore. If I were you I would encourage passengers to use the machines as much as possible, Self Service Machines are still a new thing but give it another few years and you will be surprised if people actually approach a checkin desk for anything other than to drop a bag off!!!
