TOD:
I have loved McDonald's since I visited my first one in my hometown in the early 1960s. McDonalds actually took over a business called Burger Chef, and the pricing was very much the same.
My favorite is the quarter pounder. When done correctly, it is heaven. When done badly, it is rank and foul and loathsome.
Management of a particular McDonald's is the decider in how the burgers and other delights turn out. Happily, the nearest McDonald's to me is absolutely wonderful. No meal has ever been less than fresh and tasty.
We also had a Burger King at one time. Burger King Whoppers are my weakness. I love them, plus the Burger King fries are unlike the fries of other fast food jernts.
However, the first and last time I visited the former Burger King in nearby Edgefield, I used the drive-through and brought my whopper and fries home. The whopper was hideously inedible. First, I reckoned it had been made a day or two earlier and was simply reheated. Everything seemed compressed. The fries were middling.
Had I eaten at the location, I'd have raised holy hell about it. As it was, I knew I would never be returning.
When that Burger King ultimately closed, the FB comments told me the whole story. The so-called manager was a drug addict. On-site training was virtually non-existent. Nothing was ever prepared fresh. It closed because no one would go there.
Everything depends upon who runs any particular restaurant.
