I used work for a week or two at a time in France in the 90s. My colleagues there usually went to the boulangerie or a cafeteria for lunch, but once per week, a group of them (5 or 6 engineers) went to McDonald's for lunch. I think that they started because they thought it was a bit funny and different, but it somehow became a regular thing. Some of the folks who worked in the workshop, there did something similar, though necessarily on the same days. McD's was a 5 minute walk away; closer by a couple of minutes than either the cafeteria or the boulangerie.
I never went with them. I didn't eat McD's in the US or UK. I certainly wasn't going to in France, when I could have a fresh baguette, instead.
As for Britain's most boring town.... why be so negative? Every place has its own character, we can hardly expect it to be the same from place to another. What one person finds boring, another finds comfortably familiar, and yet another finds cozy. I find the differences between one place and another interesting. A new town centre isn't interesting in the same way that a medieval town centre is, but that does not make it boring.
