It is recommended to drink 8 glasses of water a day. This is news for Rolf, who went on a 6-and-a-half-hour bus ride from Viborg to Oslo without bringing any liquid. Dehydrated, and realising his mistake, he sinks into his seat thinking about the long trip ahead. He looks up, noticing a service button above him and, maybe more for the joke of it, he presses it. Unbeknownst to Rolf, pressing that button would, in fact, lead to his thirst being quenched… but at what cost?
