If the service is bad, then I’m going pretty much anywhere else, McDonald’s is not worth putting up with crap service.

The strategy of McDs has been to saturate the market. You'll find more of their franchises per capita in your neighborhood than any other food retailer.

Starbucks employs a similar strategy.

I've lived in a few spots where people would talk about the "bad McDs" versus the "good McDs". And the split would inevitably be economic, with the richer neighborhood that could pay the better wages commanding a staff that was more professional.

But the franchise overall never suffered. They made money hand over fist at both locations.
