I think a big difference for low-income people is the cheaper end of the menu.

McDonald's (UK) has a hamburger for £1.19, or even a bacon double cheeseburger for £2.89. A happy meal is £3.89. You could reasonably feed the whole family for £20.

Five Guys (UK) charge £9.95 for their cheapest burger, and £12.25 for the bacon one. It's £4.35 for the cheapest fries and £4.45 for a soda. £20 covers one person's meal.

Fast food isn't really for low-income people. They /work/ there rather than eating there. It's just associated with them because the experience feels poor.

It's more for people who need or want the convenience.
