Food in the airport terminal is expensive

Food and drinks in airport terminals are expensive.
If you have to eat and drink, you pay 2-3 times more than you would outside.
The solution is to choose Fast food. This morning I ate at Subways. It is not what I would normally have for breakfast, but I don't loathe it , so I had the $5 combo.

Maybe these Fast food chain has to maintain contact with their customers, and they don't feel comfortable to increase their prices.
If I was to ask Killiney or food court operators, they would probably say the price is higher because of higher rental and their employees have to travel far. These reasons apply to Subways, MacDonald, Burger King and the like.
