Airport restaurants are not known for their quality of food or service.
They can get away with mediocre products because customers don’t have other options. The buyer / seller relationship is based on one of circumstance and convenience; not loyalty and fandom.
Compare that to the local coffee shop where the regulars are greeted by name and the barista begins to make their order the moment they walk through the door.
Where there is accountability, the team and products are incentivised to rise to the occasion.
