Exactly. And when there's a decision to make its human nature to err on the side that will cause you less grief.the missing point is no official gets criticised for a mistake in the Dippers favour. Send Mane off for a king fu kick to the boat race & requiring a stretcher, oxygen & more stitch work than the Technicolor dream coat & you’ll hear about if for years.
I don't think officials consciously cheat but there is a bias in most.
