I just read your great critique of Southern’t ticketing bad logic. I was thinking it could be they just never bothered to test their choice of ordering the ticket results; it’s a “that will do” mentality that is prevalent in upper management and puts pressure on the designers of these systems to “get it out there, quick, or else your job is on the line..”. So, insufficient testing and lack of the type of analysis (that you made). Smacks of no-one understanding just what the end consumers expect. Typical confusion in a company with a lack of foresight and planning.
