Operation Repo And Pawn Stars- Truth Or Fiction

I was quite naive when it came to reality shows when I first started watching them. I thought they were real and that includes Operation Repo and Pawns Stars.
Well, after watching the show, I am convinced the action is staged. For instance, in Operation Repo, when Matt rolled the car, why were there no police on the scene? When the guys get hit over the head with a bottle, why does it look like it is a breakable glass like they use in the movies.
In Pawn Stars, these people whop want to sell or pawn their things just don't walk into the store and start negotiating. I've seen it in person. They prep the employee what is going to come in, where to stand and the employees see the item before they film. That is reality?
So, it was disappointing that these are just reenactments. So, what else reenactments? I watching some cooking shows. Do they make the cooks make several takes when they are cooking? In ReHab at the Hard Rock, is that reenactments? I am pretty sure they are. Especially when they had that Texan the other night who acted like a spoiled child. That was way over the top. If that story was true, tell that Texan to stay home. Plus, when they fire someone, you don't do it on camera- that probably violates a whole lot of employment laws.
So, when Cops started, that was real but reality shows today are really not reality anymore. Just reenactments.
