If you are going to try a sandwich/slider/burger/etc for the first time should you remove something from it?

One of my friends tried Dave's Hot Chicken sliders for the first time and removed the coleslaw from it, 25% of the slider. They said the slider was bad and I argued that if you are going to try food you should just dive right into it instead of removing the flavor of the food. So my question is, if you are going to try a sandwich/slider/burger/etc for the first time should you remove something from it?
