Probably it has already happened to you that while sitting by the Danube you have thought: » I could drink a beer right now». You have looked around you maybe waiting for a miracle to happened. Like someone coming right to you shouting: » Beer, coke, cold water!»
Well, let me tell you that this is possible since there is a service called Nachschub. How does it work? You only have to call this number 0676 5433376 or check this webpage http://www.nachschub.jetzt/ and call from your smartphone (they will get your location and will come to you).
The service is from Wednesday to Saturday from 14:00 on. What do they sell? Beer, radler, wine, mineral water, coke and eistee.
