Fresh food restaurants like sushi restaurants, if it's not made the second the server says what the customer wants, they can get food poisoning. Some seafood restaurants have a time limit on how long they can take to make food.
Same with subway & bakeries, it has to be fresh, no waiting.
I mean they are necessary for some people..
Not sure about eating them
