McDonald's even at its peak was a heavy dose of salt, fat and carbohydrates, mostly empty calories, but again: cheap, fast, safe. My understanding is there are athletes that would carb load on McDonald's french fries because they were readily available basically everywhere and were very unlikely to make you sick.

Quality has slipped, prices have drastically increased, service is an order of magnitude slower...you have to be an idiot to eat at McDonald's now, the value proposition has fallen below remaining hungry.
