I’ve been in transit waiting for my next flight. While waiting, I want to spend my time more useful or more to my convenience. I don’t mind people asking me questions about certain topics so I would engage with a service that has a booth where I can voluntary go to and answer their questions. In return, I expect at least a coffee or gift card to be used in the shops. International research will be a lot easier and richer if every airport embraced and facilitated this kind of service.
