The problem is that the reports are usually from an observation made in a snapshot of time. It might be FP or it might be mechanical problems, no one knows for sure, but they walk by and see a particularly long FP line and assume something that could be so far off the path the even Mapquest would find the way out. Before if there was a long line, we assumed it was mechanical and didn't give it a second thought. Now there is a stranger in town and a handy scapegoat for anything that looks off.
So many things depend on the exact experience that one will find. Weather, light time or heavy times for attendance, mechanical situations that may be resolved quickly therefore they haven't shut down the line. There is a situation that many people have a lot of problem with. That is the limitation of the number of FP's that can be gotten in a single day. When that frustration takes hold, then any negative thought that can be mustered, will be. Change is not an easy thing to deal with, but, it must be dealt with. So, I am taking the stance that everything is OK until I am actually caught up in it and I absolutely know the reason why it is happening.
