Weirdly, the low-cost long-distance bus service in the UK has an option for food, drink, more reliably available wifi and better seating at not much more in cost if you're clever about it, in the form of Megabus/Citylink Gold. Its higher-cost competitor, National Express, stops at service stations on certain routes and provides vouchers for the cafes/restaurants there. (They also often make stops at large bus stations for upwards of quarter of an hour, allowing people to get food from surrounding shops.) And at times, you can get first class on the trains at less additional cost than the wifi would cost - with comfier seating, free wifi, multiple meals, and free alcohol.

I have a suspicion the issue isn't really the lack of service, it's that either you get nickle and dimed or the next step up is an order of magnitude higher in price.

Greyhounds usually at least stop for food. Airplanes cannot.

Greyhound takes 8 hours to go from LA to San Francisco. What choice do they have?

I've been on 13-hour transatlantic flights. They've never once stopped so I could get lunch.

Long distance buses in South America provide complimentary meals and tea/coffee.

I was provided free food on my train ride from London to Brussels, and on my train from Brussels to Amsterdam.

Which class were you in? IIRC they only give free food in the upper classes, not the basic one.

Fair enough, I was in business class and first class respectively.

It's about managing a literal sardine can full of people for half a day.

Also, any 14 hour flight will offer 2 meals and refreshments. The main concern from takeoff to landing is keeping people calm

The irony is airlines included free food to get people on board.
