It may be more complex though. The machine can be wrong, but so can your eyes. The previous customer coming to that teller with the same situation might have been someone who stole the identity of a deceased person. You can't just assume the machine is wrong because it disagrees with what you see.

This is also not the problem of machines per se, but of large systems - where different parts are handled by different people who don't know each other (or may not even be aware of each other's existence), and a set of fixed procedures (i.e. meatspace algorithms) are used to coordinate everything.
