Deteriorated McDonald's quality

I ordered a Large Spicy Cajun Chicken meal on Uber Eats from McDonald's in Hatfield, Pretoria. Delivery was perfect. Chips not bad, drink was fine, but the burger was a waste of life. I think this McDonald's makes the burger patties long before an order is placed, stores them and warms them up in a microwave when the order is placed. By the time it is delivered, I'm sure they don't care what condition it is in, which is extremely hard and inedible.
