-I can use either Mayo or MW, neither are different enough from the other that I really care.
-Any mustard is fine but I prefer spicy if given the choice.
-Ketchup is okay with fries, otherwise I usually will skip on it. On hotdogs I'm okay with mustard or mustard/ranch. Oh and Whataburger has "spicy ketchup" packets.
-BBQ sauce is probably my favorite condiment while ranch is the most versatile.
-almost any fry sauce will do for fries, i'm not picky.
Go!
