I would think if you had the rules posted and applied them equally to everyone, then there shouldn't be a problem.  I mean, the Amish are supposed to be God-fearing, law-abbiding folks.  It's not a law that encroches on their religious beliefs really, it's to protect children from bad things (smokes and beer).  If things are really getting out of hand, I would almost consider speaking to their bishop and get him to rein in the others
