The water bottle at New York Airport cost you more than $2.89, which you can get for like $0.99 at any gas station. And the same is happening with all the other items available at fancy airport food stalls.
Now many people will tell that airports have minimal resources and high security, and therefore people are not allowed to take their own food. There might be other costs such as transport, security, workforce, etc. But tell me, didn't a local vendor go through all these costs.

All these security things and other costs are a bald lie. We have been charged double/triple just because we are trapped and stuck there. People like us have to pay that amount because we don't have enough options. They make every restaurant look like some "Premium American Shit." They charge $30 for a sandwich. Last week at DFW I saw one person eating a plate of ordinary sushi for $50, which you can get for $15 loud in the market. Is this luxury? Isn't this the airports looting us ordinary people.
We can't stop flying and eating food at airports, but we can start a revolution. If you are a person with low income, you can't feed your children at the airport. But if you are lucky enough and flying from a low-grade airport, you can find mc' Donald.Oh, but security! Surely that costs more!
Believe me, that isn't the reason behind the expensive food. If that was the reason then why Airports in Japan have loads of convenience stores and ordinary restaurants. You can get food here at the same rate as the local market. My family of 5 people had a perfect dinner at Haneda Airport just for $40, and that wasn't fast food. I am not telling that there shouldn't have premium restaurants at airports, but don't we have the right to have a choice? Let's make a change together. We can't stop booking Air Flights Reservations or eating at airport restaurants, but we can make them cost cheaper ( a genuine price).

The USA can make it happen only if we rage our voice.
