Well the mennonites aren't bound by the same rules as the amish, so they have the freedom to act as enforcers, procure booze, and drive big ole trucks. The Amish just make chairs and raise barns afaik. At least that's what I learned from Amish Mafia...
When I worked for a very large cheese company doing farmer payroll, we had a lot of Mennonites in central WI. I was under the impression they could use electricity for milking but they always drove their buggies to the yearly meetings and set their big hats on the hat rack, all lined up - it was pretty cool. Some were very good businessmen, others not as much. I got to know a couple of the men and really enjoyed talking with one of them when he would call to see how much his paycheck would be bi-weekly. We always discussed gardening. They were very nice and honest people to work with. To make a long story longer, our procurement manager would tell me one of the men had a child die and he gave him condolences. The man replied that he will just have another kid. If I remember correctly, they all had Grade A milk. Some of our other "English" farms had Grade B. Grade A is a big deal for farms - Grade B means your farm is gross. Very few antibiotic loads as well that needed to be dumped. I could tell you farm stories for hours, it was the most fascinating job I ever had! Also all that organic stuff - the farms are usually nasty. None of the guys would EVER drink or eat any organic dairy.
Not sure about the Amish, we have some around here but I'm not sure if some of them use electricity or not. The one guy down the road has that canvas business, I should have nosed around more when I was there LOL The woman looked like a man, you could tell she had been working hard her entire life, very large manly hands. My BF said that when he was in high school a few of the Amish boys would party with them during the Rumspringer thing but they never became good friends with any of them.
