I hear you.
On the very few occasions I hire, I look/wait for someone who actually says they want to harvest and plow.
Otherwise I ask for someone who wants to plow solo.
I remember the days of "fighting" with other erratic harvesters and plowers who who seemed like they were so in need of every patch they could get..... like it was real money. I would just leave, because there is/was always work to do.
When my neighbors needed more $$ or pts, I would wait till they were on, and give them the work. Now we are practically all at level 100, yet we still help each other when we can.
Rude people should be banned to the other farm**** for a month.
