I'd go to an actual cashier but, you know, queues. I'm usually in and out before the first person in the queue's got anywhere, never mind the fourth or fifth. And there's also that horrid human interaction stuff too, bleugh.

Mrs.D was a teller for about a year. The pay and benefits were terrible (they made sure everybody stayed part time so there were no benefits), and she was under constant pressure to sell 'products' (credit cards, insurance) to people on pensions and welfare. This was for the most profitable and uncompetitive industry in the country.
