Not a lot of passing trade at this hour.
Not many customers stop in at this club spontaneously. It doesn't attract a a lot of random business at this time of night.
He did run the club across the road, Le Serpent Rouge, but had to move premises. There was a lot of trouble I heard. Things needed to lie quiet for a while.
The owner had to move to a new location. He had problems at his old location, and had to stay out of sight/out of business for a while until his problems were resolved.
Lost some of his best people. Very messy business. Made him nervous, and that's saying something.
Some of his most efficient employees left him. It wasn't an amicable parting. He's usually a very strong and stoic person, so for him to be nervous means that there was serious trouble behind the scenes.
I'd have guessed as much. Everyone's in hiding.
Those employees that left him are keeping to themselves; they are not talking to authorities about anything that went on at the club where they used to work.
He worked as a barman. Makes bad deals that backfire on him. He runs the café in the Place d'Arcade now. Café Metro. You never know. Might be worth a shot.
Might be worth a shot means it may be something worth trying.
