If bloodlusted, Amish easily. They're tougher than the nails they're holding their barns up with, and not prone to complaining. In reality though, they're big softies. They won't even participate in haggling unless a deal is hurting them. Watching my mom haggle with an Amish dude for dog studding service is easily the most cringe moment of my life. I had to make her greedy ass stop!
I buy my black locust/larch for raised beds from Amish/Mennonites (Fort Plain/Fonda area upstate NY) and it's so cheap when i round up to "tip" they are almost offended and very confused. It's hilarious to me and i hope they understand but I'm gonna tip them and there's nothing they can do about it.
