Complaining I Fix Harvesters Too Slow? Don't Beg When Wheat Rots

I spent five days of overtime fixing harvesters for the village, and they still complained I was too slow and charged too much. The whole village drove their harvesters over to block my door, trying to force me to back down. They said the mechanic in the next village charged less and did better work. Fine, then. Go find him. I'm done waiting on you people. But when the wheat was about to rot in the fields, they came with their heads bowed, begging me to help.
