Shin finishes as well and casually tosses his food. As usual he ignores the guards as he walks out of the restaurant. He's totally casual as they walk back towards the club, lighting up a smoke outside of the place.

He waits for someone to show up on a motorcycle. Plenty did, considering traffic and how cool motorcycles look. He didn't need to wait too long, and once a dude rides up Shin pulls Marty forward and he pushes the Valet aside. He slugs the owner and hops onto the bike, "Get on." He pulls at Marty to encourage to get him on.

So, he's not the most creative. He's mimicking Squalo, but hell, he'd been craving the rush from the first night. He felt like he needed it. Something to feel alive so he could forget about the feeling of emptiness plaguing him.
