WA Police will allege an argument over the wrong pub meal being sent to a table escalated into a fight in which guns were fired.
The altercation started at a pub in the small farming community of Gibson near Esperance on Western Australia's south coast on Friday night.
Sergeant Todd Pender alleges two groups fired up after the kitchen mishap.
"There were more arguments, which then ended up on social media that were basically, 'Let's meet at a pre-determined spot and we can sort this out'," Sergeant Pender said.
Police will allege the two groups grabbed a shotgun and a rifle from nearby farms before meeting at another location away from the pub to sort out their differences.
Sergeant Pender said during the argument shots were fired and then a fight broke out.
No-one was harmed by the firearms.
Two men have been charged with going armed while intoxicated and discharging a firearm.
The pub where the alleged fight began had only just re-opened after being used as one of the backdrops in the film adaptation of Tim Winton's acclaimed Dirt Music novel.
It is understood a scene involving dozens of local extras was filmed at the Gibson hotel.
The cast and crew of the film, including Australia's David Wenham, have been in Esperance filming for the past several weeks including at some of the town's beaches.
