This is because the McDonalds robots make you anti-nausea laden, lab-tested, uniformly, impossibly-cheap & ridiculously meat-like perfectly circular beef discs.
TGIF has real people flipping real formed meat patties that are frozen at nearby plants/suppliers and held unsafely or past their expiration date, they're lazily undercooked and hurriedly put between a bun to keep your table from getting pissy and served to you anyway.
Most chain restaurants are completely horrible in one way or another. Fake robot food or incompetent real food. Pick your poison.
