Mindy says she can't believe that they had all the trouble at the hospital over a typographical error: however, strictly speaking, it was a clerical error. The difference being if her name had been entered as Mandy McDonnell instead of Mindy McConnell this would be an example of a typographical error. However, since she was mixed up with a different patient in the hospital, that is a filing or room assignment mistake, thus a clerical error. A journalist student, like Mindy, should know the difference.
