Woah! I had no idea they did that (I live in Australia).
I read the linked Wikipedia page, but I still can't work out what the point is. Is that some form of subliminal missionary tactic? Sure the Snyder family were Christian, but why print bible citations on take-away wrappers? What's the context? What's the so-called "take-away"?
I eat there frequently, and I can't work out what the point is either. There is no other manifest connection between Christianity and the establishment.
Note that many of the verses cited are the more vanilla Christian selections. Probably the most objectionable one (especially to non-Christian believers) is John 4:16 ("no man cometh unto the Father, but by Me"), but that one is not printed on anything a customer would see.
