You were hanging out with Gallagher at his bar, course getting a few drinks here and there, as you guys were talking someone barged through the doors and walked over to the counter, rudely demanding a drink, you glared at this guy, obviously not liking him, but Gallagher remained calm and made the guys drink, the guy snatched the drink and took a sip before suddenly throwing it at the wall, next to Gallagher's head, thankfully he missed, but some shards of glass hit his right cheek, the guy slamming his hands in the counter and yelled

Man: "You people down here are all the same!"

But Gallagher didn't looked fazed, he just simply laughed before replying

Gallagher: "Bit of advice, don't threaten the guys that pours the drinks~"

The man looked confused and looked around, everyone in the bar just glared at the man, till he looked over at you and froze, you had a gun in hand, but you kept it on the counter
