The odd part wasn't really their speech as much as their manners. Some were very leery of us while others seemed to want to talk. They were all friendly though.
Back when I managed an auto paint store I had a customer that was Amish. Jonas Schwartz. Great guy with a great family. He would come in once a month or so and bring his wife and kids. They may have been a bit more laid back because he caught a lot of grief from his wife and she enjoyed dishing it out. Never knew her name, she simply introduced herself as Mrs. Jonas Schwartz.
Jonas built and painted buggies. When I asked him how he applied the paint he said he sprayed it. But I knew he didn't have electricity so I asked how his compressor worked. He had it rigged up to a bicycle and when ever he was ready to paint he put one of the kids on there. May not have been the best way to get it done and it didn't really produce enough pressure to atomize paint correctly but the paint jobs when done would rival most show cars. Sure miss that guy and his family.
And they loved to fish. Especially his wife. We swapped fishing stories quite often.
