@Pepijn got a new neighbor. He works in London and flies back and forth at least once a week. Never took the train, because the employer pays the plane tickets.
He asked for them to pay for the train. They agreed, and he took it for a spin. He now keeps taking the train, because it is easier, it takes less time, he can actually work on it, and the office is a short walk from st Pancras...
He had assumed that flying would always be faster and easier, so he had never thought of it before.
