Less than an airport coffee
Airport coffee costs what airport coffee costs. WorkOffline costs one flat white, and not an airport one: the price is set by the flat white [Your name] buys at Starbucks, Exeter St Davids, before the morning train. Checked every Monday. Coffee goes up, we go up. Coffee comes down, so do we.
WorkOffline was built for train journeys with no signal. A flight turns out to be the longest tunnel there is.
