There’s an emerging trend in hot dog eating and it’s disturbing “purists.” Two polls show that over 19-percent of Americans prefer topping their hot dogs with mayo. It’s such a thing now that people even complain online because Costco doesn’t have mayo as a condiment for their dog. The debate online is heated with those opposing the idea saying things like “Mayo on hot dog is a disease, get well soon” and those who love it noting “Mayo and ketchup are a must!! And now I think I need to carry mayo in purse just for this.” There’s even a Reddit thread devoted to mayo and hot dog lovers. Maybe it’s worth a try.
