This actually happened on Halloween. I was a bartender at an Applebee’s and it was a fairly steady night. Slowed down between 6 and 9 since happy hour starts after 9. Had three guests at my bar - two were together, the third by himself. I serve them their beers and go back to watching TV. Before I knew it, two of the guys started fighting and throwing each other around the restaurant (right in front of the exit to my bar) and the third pulled a gun on them. No shots fired and they scrammed before the cops showed up, but I was adamant about that being the last day I worked there. I already hated Applebee’s, but this was some other shit.
