Anti-aggression campaign Belgian train company

This is a photo of a train conductor with the text "Can I see your ticket, please" and the effect of smashed glass. It is part of a number of similar photos used in a campaign against aggression towards train staff ran by the Belgian train company NMBS / SNCB. It's a powerful image that draws attention. There was a limited amount of interactive versions where you could touch the screen and stop aggression (the broken glass effect disappeared as if it was healed).
