I've ran into that fight on duty roulette twice.
When the fight started, no one really knew what to do except for one person.
That person said, "Who is on cannons?"

I never had a chance to operate the cannons before and I said, "I never tried using cannons, how do I know when to shoot the cannons?"
It got quiet for a good 20seconds, then when that person asked the same question, "Who is on cannons?"
People started leaving left and right and I felt so bad and frustrated.
