Well if you know it's "snack boxes" (commonly refered to as "Heart attack in a box") I think it's better to go down to Topps BBQ in Frayser and order yourself some "to go" bbq or go to Backyard Burger in Hickory Hill and get yourself some burger special. Probably much healthier than those salt laden cheese and dried sausage stuff.
Memphis airport.... I wouldn't count on gettin' any food from the concessions. Surprisingly, some items may not be sold because they don't feel like making it. (or they just don't like me.... ) Only thing I could count on was some overpriced Interstate BBQ.
If I wanted dried up pinky size sausages, I'd go back to my old boyfriend.
