Starving in Germany on a Sunday

Ok I exaggerate a little bit. I got back from a trip to Graz Austria at 22:50 last night. But today is Sunday and so there are not many shops open. I had forgotten to get enough food for today, so I only had tinned food. On meal from a tin a day is OK, bu two? Luckily I had many tins of tuna, so I had a  reasonable salid.

It would be so simple if I lived in the UK, because I could have done a quick shop at Tesco.
