You can keep talking about kfc. I want to say that when the store opened, it was better, and the food and waiting time were better, but now it's the other way around, there's no assortment, the delivery is long, they don't have time to issue an order, they even forget to put an order sometimes.
You don't have to do it one time at a time. One time it's very tasty, another time it's an old chicken with a smell. The old oil smells unpleasant. So my advice is to change the oil more often. Mostly rude staff who change frequently.
