Just to see a patron come hurling into the bar between the two. Luckily the quartermaster moved out of the way in time, allowing said random patron to go flipping head-over-heals over said bar and into the bottles of cheap liquor shelved on the other side.
The source of the disturbance was another young woman, also in her early twenties. Her back was too the assembly at the bar, so all they could see of her was her reddish-brown hair tied up in a rather messy ponytail, as well as the back of her brown bomber-jacket and faded blue-jeans.
"You think you can cheat me!?" she bellowed at the people standing in front of her, a group of three male card-players who had been on the wrong end of the flipped table.
Said men were just getting to their feet as the woman threw off her jacket, revealing the white tank-top underneath. They didn't get any time to respond to her, however; as she was almost immediately upon then, using the momentum from her sudden sprint to power a snap-punch into the left-most card-player's face. Even as he went soaring out of sight, she had switched the central man, who raised his fists to block her initial blow. The strike was indeed blocked, but she-followed up by spinning around the man to the side and chopping at the side of his neck.
The third man tried to pull a gun, but the spin had moved the woman just close enough that a quick upward kick sent said weapon straight up into the ceiling. She then tried the close the distance and strike again, but he managed to block the first punch with his hand, which he clamped over the woman's fist. She then lashed out with her left arm, only to have that blow caught too. The man smirked slightly, just before she lunged forward and headbutted him in the jaw. He let go, took a few dizzy steps backward, then flopped onto the floor.
"What!? Is that all!?" she roared in a victorious voice... just before the gun she'd kicked into the ceiling came crashing down onto her head.
She immediately went rigid, then cartoonishly fell to the floor unconscious, the camera angle only showing her feet come back up into view.
