They are polite as a rule but elders will scowl or ignore you if you have alcohol on your breath. Then I wonder why you set up your tray of delicious peanut brittle and cheese in front of a tavern (instead of setting up at the weekly farmer's market, which I still don't understand), my Amish dude, but whatever. It is what it is.
We have had extensive barn work done by Amish crews, excellent, unsurpassed.
Many Amish communities have no prohibition on drinking alcohol. I regularly always walking out of convenience, stores with six packs or 12 packs. I have bought alcoholic beverages for Amish bishops that I was dining with. Etc. etc. it’s only some communities that turn a sour eye at it.
