How long do you think Gus knew about Jesse skimming and selling his/their product behind his back?

I've never really given it much thought, I guess I assumed Jesse was getting away with it since Gus never moved on it and it seems Gus wouldn't be kopasetic with Jesse selling in his territory.

That being said, Gus also isn't the kind of person who doesn't know what's happening under his own roof. If anything Gus is over protective and known to both the audience and the people in the show, as the guy who always knows what's going on. He's usually more informed on the other gangs and people out side his network then the people who are within those networks, so it stands to reason, if Jesse was skimming, Gus should know about it from the very moment Jesse even had the thought.

I get the impression the show wants us to think he didn't know until we know he knows, but that stands in contrast to him as a character. So what do you think?
