I remember when Google rolled out a hands free payment system at McDonalds and the identity verification step involved speaking your initials to the McDonalds employee. Despite so much automation (not even needing to pull out your phone) the system totally failed on the verbal interpretation of the initials: "Did you say "J" or "G"??" and gesturing the shape of the letter with fingers.
