How come the store bought sour cream and the sour cream served at restaurants taste so much different?

In my opinion the sour cream served at restaurants taste way better and is more rich and fresh tasting than the sour cream that we buy from the store? I have been searching for restaurant quality sour cream at stores for a long time now but I can't find any! Do you know where restaurants get their sour creams from? Do they make it fresh themselves? Why does it taste sooo much better and different compared to the sour cream that is store bought?How come the store bought sour cream and the sour cream served at restaurants taste so much different?
the restaurants sourcream may be some cheap industrial brand idk im just taking a guess
Restaurants usually use Daisy brand sour cream.How come the store bought sour cream and the sour cream served at restaurants taste so much different?
the restaurant variety is usually soy based as it has a longer shelf life.
