Customer satisfaction

Customer satisfaction measures the success of a Sim's restaurant in The Sims 4: Dine Out. Customers are a major part of a restaurant other than the employees themselves, as the consumer that purchases the meals the restaurant makes, the restaurant gets Simoleons that will be divided for the pay for the staff, owner, and the restaurant itself.

Customers satisfaction can and will effect a Sims restaurant. Multiple customers will give their review dictate what star rating the restaurant has, and in turn determine how good the populace think of the restaurant.

Star rating
On the Panel of Owned Businesses, restaurants display a 5 star rating in which will be influenced by the collective of customers and restaurant critics.

Every customer enters the restaurant with a star floating above their head. All customers start out with a neutral 3 star rating and will either go up to 4 or 5, or will go down to 2, or 1 depending on how their experience was with the service, meal and ambience.

Star Rating is important, as it is a public review of how customers think of the restaurant. At 1 star, the restaurant will have very few customers coming in, but as the star rating rises the more popular the restaurant will become, and more customers will come in.
 * At 1 Star, 5 customers will come in
 * At 2 Star, 7 customers will come in
 * At 3 Star, 10 customers will come in
 * At 4 Star, 14 customers will come in
 * At 5 Star, 20 customers will come in

Increasing the star rating is done by improving the service of the host, waiters, and chefs, as well as how well they treat the customers. The better the customers are treated, how fast they get the food, and how tasty the food is, will greatly enhance the customers opinion and help the restaurant to slowly become better rated.

Increasing customer satisfaction
Customers have three different needs when they come to the restaurant: Meal Quality, Service, and Ambience.

Meal Quality, is dictated by how good the chefs are, their skill and emotion to work as a chef can greatly effect how the meal is tasty.

Service, is dictated by how well the hosts and waiters treat the customers as well as how fast the waiters are to deliver the food and make sure they don't drop the food.

Ambience, is dictated by how decorated the place is and the aroma of the music.

Meal quality and service are highly dependent on employee work and they must be of the required skill and mood in order to work at the restaurant.

Restaurant Critic
There are unique customers that are paid to be a customer by going to restaurants and trying out how the service, meal, and ambience is. What matters is that restaurant critic's have a public opinion to many other people and their opinion can greatly effect the star rating, so it is mandatory to make sure restaurant critic's aren't left out.
