Ok, if I was on my own, pushed for time, then yes, they are useful. But, trying to return, renew and borrow books for me and my Ds on separate cards, while v active toddler tries to feed coins in/make a break for the door, and then make sure the correct books go on the shelf or bin, it's unecessary stress, it's a fucker. Meanwhile there are 2 librarians 2 feet away from me doing bugger all having a chat. (Dons coat)
