Is Bacon on a Burger a Condiment?

No, bacon is not a condiment. Condiments are just one thing that can be used to enhance the flavor of food; not everything that enhances food's flavor is a condiment. For instance, different wines are used to enhance and compliment food, but wine certainly isn't a condiment; bacon falls into that same category. Bacon bits are just bacon, regardless of how they are prepared, so they're not a condiment either.
