We had a PCM about the proper way to transfer odometer readings to the DIAD. Someone in a cubicle with far too much time on their hands has noticed that some drivers will round the odometer up to record their ending mileage but will round it down to record the beginning mileage the following day, thus "stealing" one mile. We are now instructed to round our odometer readings up. Our center manager was actually instructed to verify odometer readings of known offenders. Amazing.
