That bugs the heck out of me as well.The hurry along and the cutting/shortening of segments on OTC to make sure they're right on the deadline so the....... rerun of the show before it can start? Why the F are they in such a rush?
It comes down to a weak Producer and Host who can't stick to a timeframe.
Even if they do run a few minutes over, all it means is someone in the Control Room cutting a few ads in the next hour to get the schedule back on time.
All too hard for FoxFooty.
