That's some big brain management idea right there. I suppose there was probably a reason for it but it sounds like when you do make a change it would be likely to cause an error because of poor ergonomics.

I've had the same experience while building EMRs and pharmacy inventory systems. Clients actually requested for bad UX, so that the people doing the data entry will double check that they've entered the correct values because fixing them is more painful.
