From the tables to the loud customers, then back to Seamus, Gregory turned his head to look, making mental notes as to what needed to be done. Simple tasks like these were not hard to remember, and he nodded once to show he understood. It was a good thing that Seamus warned Gregory to be gentle with the arguing men, because Gregory decided that breaking up the argument would be top priority and that he'd do so by breaking up some heads. Maybe it was something in the way that Gregory had cracked his knuckles and pounded his right fist into his left hand to prepare himself for a fight that suggested to Seamus to make his 'gentle' comment in the first place.
"Uh... OKAY BOSS!" Gregory said, shouting out the last pair of words so Seamus could hear him, though he had already disappeared through the doors. Whether or not Seamus could hear was irrelevant, anyway.
He'd have to get a rag or something from the bar to clean those tables, though. Probably get one from the bar.
