When in the MP I always ask for solo workers who do both harvesting and plowing. I also can't be bothered hiring seperately. It might be antisocial to some, but it works much better than half a dozen people running round in a frenzy, getting frustrated and disappearing. It gives them a boost to level up too.
I had a really slow one this morning, level 8. I had to think back to how I was when I first started. With the 4x harvester, plower and seeder I'd probably be slow again
And yes there are rude people, just hit the ignore button and you'll never see them again. I love that button.
