I was once stranded in Cancun, Mexico during Hurricane Wilma, and was in a shelter where they were serving hot dogs. The couple in line behind me from New York City kept talking in amazement with what they were seeing - people putting ketchup and other things besides just mustard on their hotdogs. I being from the South turned around and said, "yep, we put everything on them"... And it's true - the traditional dog in the South is with ketchup, mustard, onions, and relish... sometimes cheese too. Then there's chili dogs. I'm actually a mustard person, myself... I love boarshead spicy mustard the best... or grey pu pond. I've been known to put ketchup on my eggs, but hot sauce is better. Hope I didn't gross you out. 😀
