Health inspectors come in to make sure the place is properly cleaned, that employees are following hygiene guidelines like hand-washing practices and proper clothing and footwear. They check for signs of pests like rodents and bugs. You have to prepare food a certain way to make sure things aren't being served undercooked, as that could potentially make people sick. If you're doing anything raw, there are even more rules about that, because uncooked foods can sometimes cause a lot of problems if they're not properly stored and maintained. And that's the other thing. You have to keep your food stored in ways that prevents it from spoiling or so that bugs and rodents can't get into it.
There are a lot of regulations and rules to learn and follow when running a restaurant. I used the nightclub as a way to learn about all of that while saving up money. It's been a learning experience here, and I'm always making sure the Sizzle & Sear is following the rules from back home, just to keep it all current in my mind. I still don't want to make anyone sick... even if it's just virtual here, and even if the Wardens aren't really following things as closely as a health inspector back home might.
