I have met Samuel and Glenn. They are friendly and cheerful, and they always bring a cake with them. It’s different, as it doesn’t usually happen in Sweden, so it’s quite amusing when it happens. It’s fun and distinctive. However, I don’t have any specific suggestions on how they can improve.

Can you give an example of how you would be affected by a sudden power outage? “It would have been troublesome, our website would have gone down, the entire region’s travel planner would have gone down, real-time information would have gone down throughout the region. It would have been a very difficult situation for both us and our customers.”
