Squalo might be wondering that too -- though it's more of a case of how much liquid can he process without having to either piss or throw up than actual issue of drunkenness. Although his gaze might look a little unfocused when he stares at the bottle again.

Then he turns and decks the guy who spun it.

"Fucking seriously? Third one and that guy's only got one?"

Nonetheless, he's picking it up. Alright then. All or nothing, right. He's just going to pour it down his throat this time, looking like he has some trouble staying upright once he's done, but nonetheless, he'll be preparing the next bottle. "Ha! Watch and learn." 50/50 and he'll cheat slightly if he has to. He's not downing a fucking fourth one.
