One of my 4 kids wanted only meat and bun growing up. I never had a problem asking for plain at McDonalds in 3 states and receiving nothing more than meat and bun. Thankfully, he outgrew his fear of flavor and will now try many things I couldn't have imagined when he was 2 and asking for a plain hamburger.

I had a craving for a smoke flavored hamburger last week and went into a Burger King for the first time in a few years. The result was "wet". It must have had several tablespoons of mustard/ketchup which completely overwhelmed the poor little patty. I should have asked for plain.
