So after two drinks one closed out and headed out the door.....
I noticed the one who'd left had left a pair of keys on the bar, so I handed them to the friend that stayed and they ran after and got stopped by our little alcove with the mail slot where a door handle could be.
A moment after, our former doorguy (whom I got my break into the bar from) who was outside for a smoke, came back in to mind his Woodford.
"Wow" he said....
"They must have gotten in a fight"
"The first one got about halfway down the block before the other one came outside, looked around and then ran about 10 feet, made a very large noise and threw a fuckin pair of keys at her. They are still out there going at it."
I filled him in and we went back to our previous businesses as straight faced as possible until said person closed out and left.
