I was thinking of it as being more like a made guy from Chicago ends up living in lets say Saratoga,where maybe the Genovese have a flag
The Genovese boss and the Chicago boss both agree that this Chicago made guy can run a string of strip clubs in Saratoga or whatever other business he has talents for,whether illegal or semi legal. Perhaps the case is that the Genovese think the business is a great idea,but have no local man of their own capable of running that business.

Both bosses, the Chicago boss and the Genovese agree and both agree that they get a piece from the profits even if the Genovese boss gets more than the Chicago boss.since the Genovese have the flag there
Also this guy from Chicago may or may not include Genovese Family Saratoga guys in the business as emplyees,managers,etc

So in other word a Chicago made guy is given the okay to operaate in a town that under Genovese jurisdiction,because the Genovese Family as well as the Chicago family will both profit in whatever prportionof the wealth they agree on?

If such an agreement existed would tht necessarily mean that in effect,the Chicago Family now had planted a flag in Saratoga?
