A woman recently got canned from her barista job at the airport, but she wasn't going to leave quietly -- on the contrary, she went kicking and screaming ... fighting everybody!!!

This wild video shows an all-out brawl going down at a Harvest & Grounds coffee shop within the Hartsfield-Jackson Atlanta International Airport Saturday -- and the lady featured as the main character here certainly wanted to scrap with her managers/the team at large.

Indeed, hands were thrown ... and bodies were flung ... and it lasted a damn long while too.

As for how this mayhem even got started -- cops are saying it all had to do with a disagreement between this woman and a coworker ... who were apparently bickering about espresso shots, at least according to the police report obtained by the outlet .

Unclear what exactly the issue was ... but this argument escalated into what you see here -- with her managers getting into the mix to hold her back from attacking a person behind the counter.

Unfortunately, that didn't stop her ... 'cause she made a big leap to get over there.

As you can see, her boss is openly asking if folks are calling cops -- and the police did, indeed, show up eventually ... but not before a chair almost got chucked in the process. When officers arrived, this woman was long gone ... and yes, she was terminated as a result.

Can't say this with any certainty ... but it sounds like somebody missed their morning Joe.
