Any mass-scale business that is required to hold customers on their premises for hours at a time in a space-confined area is always going to be challenged with customer service. Combined with the modern consumer who is taught they're always right, and it's a recipe for dissatisfaction. I travel a ton for work and have learned to let things roll off my back. Yet when I travel with friends and family, they will always find something dissatisfying, even if it's on a car trip. Nasty bathrooms at a rest stop, a missed exit, etc. are no different than a flight. When 99% of things go right and you travel at 800mph for hundreds of miles for less than a hundred bucks, people let inferior coffee ruin the entire trip for them. God forbid the complexity added by doing it with a few hundred other people.
