Well, some stuff can be centralized, like burger production, or ordering million gallons of Coke. Some stuff, however, has to remain local, like labor, or real estate costs.

Honestly, that's the only reason I'd ever go there (and even then only very rarely). Not because it was "good," but because I knew what to expect. Although... I should probably qualify that bit about expectations: Last time I was there was probably early '22 and only because my dad was in hospice with a craving for one of their menu items (and fries). I bought a BigMac for myself, got home, and saw that the bun was moldy. No thanks!
