A common problem for new foreign residents to Germany is to find closed supermarket doors on the afternoons of Heiligabend (Christmas Eve), Dec 24th, and Silvester, Dec 31st.
Our local supermarket, EDEKA, puts up the following announcement every year. Even spelling mistakes get recycled in Germany.
Please note that the correct spelling is Silvester, and not Sylvester.
Sylvester was a Pope and is a Looney Tunes character.
