Big Brother at Warsaw metro

I was on my way from a traditional, 10th by now, Christmas eve with my university friends. It was past midnight, not that it should matter. At one of the stops we hear a man’s voice speaking over the loudspeaker – usually used only to announce emergency notices. He says something which only became understood after a movement of a passenger awaiting for a train on the platform: Please get up from that bench/Proszę się podnieść z tej ławki.

The passenger who reacted didn’t even seem to be laying down. Maybe he wasn’t sitting perfectly straight, but certainly did not look worrying, agresive, desruptive, abusive, violent, or any etc. He may have been tiered, maybe tiered after a beer, maybe after a long day of work, but not a homeless or drunk. Just a regular young guy, definately either a high school or university student, not a future looser. So why the Big Brother remark over the loudspeaker? haha?
