I have the opposite problem, my players love to infight about everything. It’s all roleplay, we are great friends and we laugh the entire time, but one of them has assumed the role of Captain of their ship, and barks orders at the other player’s PCs and it just devolves into chaos as the Orc Barbarian and Human Wizard try to interpret the wild and dangerous orders of their Goblin Captain. I haven’t tried it, but I think if I didn’t reign them in, they may go at it all night.
