It's probably similar to the way Texans feel about beans in their chilli. (Did I get that right?)
On the flip side, I lauged my butt off when Kerry asked for Swiss cheese on his Philly Cheesesteak from Pat's King of Steaks. As it is, I can't get down here what I used to get up there on my cheesesteak: Cheese Whiz! :)
I guess it just depends on the attachment that we have to particular elements of our respective cultures. Hot dogs? For me, as few as possible, except when the ambiance demands it. :)
