Admittedly, when I was in Israel, I had to do a bit of mental re-adjusting before I was able to eat in the KFC there. 🙂
I actually believe that “the mental re-adjusting” required to eat in a kosher franchisee of a non-kosher chain restaurant is part of the reason that some have hashkafic issues with it. I find it difficult to articulate my personal (hashkafic) issues, which is why I haven’t commented much on it.
