Forewarned counts for two, but the NS notices that a lot of people are not paying attention and the company is secretly disappointed by that. “We just find it really annoying when people lose their stuff later. By warning them they can be a bit more alert. In the train we also have a number where people can call or text if they see someone acting strange. Then we can take action and track down such a person. Of course you want to catch them in the act.”
