Obviously staged (here's why)

I know this show is fake, but I'd like to share my observations

1. How is it possible we're able to hear what the waiters and customers are saying who aren't in on the sting? They're obviously all miked and know it's a show

2. In the episode where the waiter is giving alcohol to college girls without IDs, at the end of the episode, you can see he's wearing an ear piece

3. Even if you have employees who are stealing from you, it's highly unlikely they all do it every day, let alone on the day you decide to install hidden cameras
