>but how do I know I'll have more leg room anyway?
google flights literally has a legroom indicator.
>Maybe they'll just upcharge me.
the common upchargeable items (eg. baggage) can either be found on google flights, or are easily searchable.
>Same for restaurants if you're a traveler and don't have time to get familiar with the reputation.
That's basically a perennial problem with tourist trap restaurants, no need to invoke "enshittification" or corporation bashing.
You can go off marketing, but every place will try to present it's food as unique and well crafted even if it's premade.
