Anyway, there is such a thing as a kosher subway's! I don't know where you guys live, but in certain Jewish community of people I know, they recently got a subways with a kosher certification. (there are other "nonJewish" places that serve kosher-only in certain store locations, ie kosher dunkin donuts, etc such places market to areas with a big frum population and not many kosher choices to eat at)...
For those people who are so tempted by nonkosher food that they can't bear a discussion of it (which means you are probably still working on avoiding these foods and eliminating them from your diet, so I must congratulate and encourage you for doing your best to take on the mitzvahs of kashrut, and urge you to keep up your effort), I would suggest that you avoid looking at such a thread. If the name "Subway" or McD's or anything else in the title is enough to drive you crazy, then just imagine the person means a "kosher Subway" (obviously such a place has less on the menu than normal subway's), be sad you're not in Israel where just about everything is kosher, and avoid clicking on the thread.
(I believe there is one kosher mcdonalds in Israel if I remember correctly... of course tons of kosher burger places though).
