The point of eating at McDonald's is not to get the world's best burger. It's to get a McD burger which always tastes the same no matter where you are. They don't really even taste like regular burgers, they taste like McDonald's burgers. People aren't dumb, they know approximately what the burger at Bongo (or wherever) will taste like. But you have to figure out what they put on the burger, what to drink, etc. At McD you get the same thing every time, no fuss. It's much less cognitive load to eat at McDonalds, plus it's almost certainly cheaper. Everybody has their reasons.
