He strongly considers it, honestly, because come on. That's a hot trope right now. But lucky for the both of them, he's easily distracted by Cooper's drink order.

What the fuck kind of combination is that?

Judging by Ghoul's face, he thinks it's criminal. "Seriously...?" He's a baby's breath away from making some sort of comment along the lines of having done Cooper a favor by trashing his drink, but, well, he's probably already done enough damage today. "Um, okay. Sit. Stay. Play some candy crush for like five minutes. I'll be right back..." Ghoul slinks back inside before any arguments can be made.

True to his word, soon enough he returns to where he'd left Cooper, extra cup in hand. The lines had thinned down a bit so it took less time than Ghoul would've expected, but there's no guarantee the kid's still around. Which would suck. Because then he'll be stuck with a gross milky tea.
