@5864a332 nooo! Those are reusable bottles. People should take them back to the shop, but if they are too lazy to do that they are supposed to leave them next to the bin. There's a deposit on the bottles, so they are quite valuable for bottle collectors. If you throw them in the bin, bottle collectors have to rummage through the trash. That's why they want you to put bottles on the floor. They even put stickers on the bins saying "Pfand gehört daneben" 

 @2270456b I took this pic in the U-bahn, where the bottles move around all the time, often spilling beer.
