Some random plebeian has just spilled your pint, and this has just set you off. You stand up, push the drunkard over, and draw your longsword. A few people are watching at this point.
You plunge your sword deep into his breast, hitting his heart. You decide to loot his body, and find another fifty gold coins, a shield, and a shortsword that could use a sharpening.
The other patrons are not enjoying this display of testosterone. The bartender yells for you to get out, and threatens you. You don't take this threat lightly, and jump over the bar to face him. He cowers in a corner as you bash him repeatedly with the pommel of your sword.
Some of the other patrons have left the bar, while a few stayed and have drawn their swords. Three men on the other side of the room are ready to brawl. You jump the bar, shield in one hand, longsword in the other, and rush them. One swings at you, you block, and parry another hit from the side, followed by a stab into the stomach. The man in the middle stabs at you, which you deftly dodge, and then counter with a spinning swing to the back of his neck. He drops and two men remain.
The wounded man takes a fatigued swing at you which you deflect easily, and then kick him to the ground. The other man charges you, but you step out of the way and trip him. With both men on the ground, you finish them both off, and loot everyone in the room. You now have six hundred coins total, and have just acquired a new bow, a steel helmet, steel boots, and more swords than you can carry.
You gear up and leave the pub. Time to get some food. You can go to the market, or go hunting with your new bow.
