McDonalds used to (don't laugh) be a company that demanded their beef be top grade.
I guess they've succumbed to the siren song of cheap shit packed by pajeet.
Some of the food safety protocols used by NASA were originally created by McDonalds. Honestly, if you are traveling it is probably one of the safest places to eat and not get sick while on travel.
Yes, that's their thing - and something that Kroc insisted on. The McDonalds in your town must taste just like the McDonalds in the city 1000 miles away from you. You knew what you were getting because it was of defined quality.
Is it really good for you? No, of course not. But a burger, small fry, and a drink on the go when you knew exactly what you were getting was invaluable. One more thing we've lost.
