Also Brom here's a good question, How will Charlie's meeting with the Tong and my meet with the Yakuza effect team over all. Tong and Yakuza are not friends as far as I can recall in the present day.
I'm thinking that we are "end users"... so it doesn't matter. Think of it as High school again.
your a "jock" but you go and visit the band member, while I visit the drama, chess or debate team. WE are dealing with them as characters and individuals. You don't tell others about what you know and can do. Chances are... they don't really care. we are just a "means to an end for them". It all about WHAT can you do for me, funk everyone else kinda thing.
You as Casino might get a job offer, you have two choices. Help or not help. that is kinda the same for me right now.
But..... like Brom said every action has a reaction, right?.
So, in short it doesn't matter whom we deal with mostly, its only our action as we deal with them, you let them know your business then expect them to dictate things to you.
Good luck to you with your meeting and seize the day!
