Sometimes I don't know if they're sociopaths or just plain stupid, because I had an associate that took forever to vouch and when done, often missed the entire point of the workpaper. Like for cutoff testing, he would put N/A in the date. After showing him step by step how to do it by doing 1 sample as an example and asking him to vouch the date again, he would just put Sighted to invoice # dated #/#/# instead of following the format in the first sample we did together.
