How common do you honestly think this situation might be? I know an ENTJ who rents office spaces to people. He uses his own building for his business, but also rents out spaces within the building. It's one of those "let's all pool our resources together" (not money, but conference rooms, cleaning fees, internet access, business friendships, etc.) and help each other run successful businesses. And we'll all be one big network for each other in the process.
But, here's what seems to happen. When one of the small start-ups in the building begins to do well - when it really begins to bring in some serious cash-flow, ENTJ tries to get involved. Not so much in a "let me run your business" type of way. It's more like since it's happening under "his roof", then he's not going to be left behind - he wants to somehow reap some of the benefits of the upstart too.
The way I see it is that it's "cut and dry". You rent space to people. They pay you for it. If they become successful, you have no more "say" in their business operations than you did at the beginning.
At one point, one of the entrepreneurs was extremely upset because they said they suspected the ENTJ of "going through their stuff at night" when nobody was in the building. They left important paperwork and files in various specific locations (so that they would know if they were moved) and when they would come back in the morning, the paperwork and files were in slightly different places on their desk or in their files.
So, imagine you own a building and you rent space to young, creative entrepreneurs. One or more of them really begins to take off in their business - pulling in low 7-figures annually. Are you more prone to just say, "Wow! Congratulations on your huge success." Or, are you more apt to want to have your hand in the success of this person and when they deny you access by *keeping things professional*, would you get offended or start getting nasty in any way? Be as honest as possible in regards to what you might be thinking. I'm not trying to pick on ENTJ's, just trying to understand how Te would handle this type of situation, especially since Te wants to direct how things go.
