Patron Badass
Sometimes, NPC's don't want to talk to the bard because they have no affiliation with them. A fighter may have been around enough to make some friends in similar lines of work, and their friend doesn't want some fancy pants bard speaking for their friends. Mechanically, the friend would be indifferent to the bard but friendly to the fighter.
Sometimes, an NPC will just directly talk to the fighter, because it's awkward to see a group of people and literally only one person ever opens their mouth.
Sometimes, only the fighter has certain information or knowledge on something specific. Something necessary to convince someone. Sometimes, the bard can't really think of a logical progression in the conversation but the fighter realized they know something interesting.
