Kinda of an ironic situation for someone who is Jewish, and all of the sudden demands to see "papers", IMO.
I've asked, several people in fact, which is the same thing.
Neither do I find anything at all ironic about a Jew asking an individual for identification, "papers". I've done it many times in my life, in many different contexts, including employment, as have many friends. I admit to being puzzeled as to the meaning of the "Jewish" comment, are you suggesting that Jewish employers are lax in documenting employees, as contrasted with Christian or Muslim employers?
