The fight in this movie may have been, as you put it, somewhat stereotypical -- romanticized, perhaps, and maybe even a bit of a cliche -- but it wasn't out of place, and I think the scene played pretty well, from start to finish.
Eh, I just saw one big cliche made up of a bunch of smaller ones. There was the group of meatheads who needed to "defend" the poor defenseless woman from the smartass hitting on her, there were all the shots at people from rural areas, including the persistent suggestion that it's unusual for people from rural areas to be smart, the action movie bar fight scene, the physical humor of a woman's breasts getting groped even though the guy supposedly didn't mean to do so... Really just a lot of cliches. And where I come from the police would have been called and the bartender would have pulled the shotgun out from behind the bar and told them to get the hell out of his bar as soon as they got out of hand.
