Hey John - you bet, if they don't keep their fryers clean, you're eating some nasty bacteria.
I always found KFC good for a colon cleanse in about 30 minutes, often enough that I learned to time my consumption vs availability of a porcelain throne.
Haven't had that experience with other fried chicken - and never got sick - but I don't eat fried foods very often.
Naugles - I remember them from decades ago, at the time they seemed pretty good.
