I remember dealing with a business department that had the task of entering weekly personal and business company car mileage data for all the company car holders. With about 200 car drivers, you'd expect no more than about 1000 records a month to be inserted to the db, not too onerous. They recruited a new person and trained them up themselves instead of asking IT dept to do it for them. At end of month, new user was distraught. They'd entered all the data and they only had one row in the database. They'd kept querying the same row and updating the registration number and mileage repeatedly. At least they weren't asking for a reference though. Felt sorry for the noob, it was his department's fault for poor training and poor supervision.
