I think you misunderstood my point, self service machines are (in some cases) quicker because they can afford to have more machines than they would have people.
So for example in the photo above there are four self-service machines. How often do you see four staff members running the on-ride photos?
Plus they often have translations so work better for those that don't speak English.
No, I've completely understood your point. Demand for machines has been created by manufacturing queues for manned kiosks. So in that sense, they are quicker as you are less likely to queue for them. This works better at train stations and theme parks than supermarkets and restaurants however as the product you are buying, a ticket, is a very simple one to vend.
There was a time when there would have been loads of people behind photo kiosks at Towers, your local train station would have had loads of manned booths and your local Sainsbury's would have has 28 manned checkouts.
All seems a long time ago now though...
