It seems like if the words of the elf would have been a summoning spell. A summon dwarf spell. Five dwarves jump at the chance, but seeing the competence, they start to push each other, grunting and bickering and shouting. An additional dwarf joins the fray, a red bearded dwarf. A Firebelly dwarf. Not your regular dwarf, mind you.
He starts the most impressive brawl the tavern has yet seen. Punches fly from one dwarf to the other, but the Firebelly dwarf's hands seem to be made of adamantium, each hit seemed to almost knock his opponents down, but the stubborn dwarves don't go down so easily. As the brawl advances the other dwarves realize that if they don't take down the Firebelly, they won't get not even a single drop of free alcohol. Deftly fighting against all odds, the red bearded dwarf beats up one dwarf after another.
With a huge smile on his red fat, beat up face, the Firebelly dwarf approached the table with his prize, the alcohol offering elf. But when everybody thought the battle was over, the defeated dwarves jump over him, trying to restrain him.
It is them when everybody sees the legendary might of the Firebelly clan been triggered. This special technique was practiced only by this clan, and used only on rare occasions. To learn the technique, the clanmembers are deprived of alcohol for an entire week. After that, they are left without any protection or weapon, and must make they way through a group of their brothers, armed up to the teeth to claim a mug of premium ale, resting on an altar. Most of the clanmembers passed that trial.
Using this hidden power, the red beard emerged from under the pile of dwarves, and threw each of them crashing to the walls, as he shouted and yelled like an animal.
After that, he calms himself and sits next to the elf. "Howdy, me name be Muzdum, please ta meet ya." the dwarf says smiling, as if nothing had happened.
