Marcella observed the yakuza guys in there. They all were sitting with their backs straight and had a hardened look on their face. She's used to seeing men with a no-nonsense attitude and she was not intimidated by them.
The group of men were all wearing suits like office workers. If anyone saw them on the streets, they would think they were working on Wall Street. That's how decent they were dressed. One of the guys was sitting silently while the other guy was observing his face as if he was waiting for his command. The other guys were observing everything going around.
The silent guy looked at her directly noticing her stare. Marcella didn't look away. She was not staring at him; she was observing him. He would know the difference.
