I've had several bad calls on me over the years. A couple off hand were from bad to no vantage point. Shouting match included. One ignorant call on a split hit with the person watching. I retained the innings those three times but not without ruffling feathers and none of the callers were convinced. JFTR I relinquish the inning if I did foul. Sociable stuff I sometimes point out possible bad hits I've shot and give the other player an option. They don't always care but probably retain the tidbit.
