I think it's been said here before, but seems to me that the show aspect is a gimmick to get people to eat at Rocco's. They'll end up with a Hard Rock Cafe style clientele (which is probably why the food is so mid-brow), and they'll be crowded for at least a little while. I think it is within their plan to generate the mishaps that make the show interesting just to create the buzz; normally a new restaurant would try to hire the best - in this case "the best" might mean most likely to get yelled at, drop a plate, ect. I figure by now they have a staff intended to do business.
