I had a colleague who was very fussy about Kosher observance (she was part of a left-wing Conservative synagogue, if that makes sense), and she was convinced that the whole Kosher wine thing was a crock. Which doesn't stop some very reputable establishments from making it, including a few good Bordeaux Chateaux.
We had an Orthodox Jew living on our floor freshman year and his default snack was Entenmann's pound cake eaten with disposable utensils. He would do pizza, though. When we didn't want to share and thought he might be returning from the library we'd order sausage or pepperoni just to be sure.
