Sunday shopping turn me on too much as much as being open for lunch hours. That aspect of life in Madrid drives me mad. It's one of the main reasons why I shop only at the big chains. I can not understand for the life of me why someone would want a 2 hour break at lunch and then work till 8pm at night.
On the other hand I came via Germany where life ends at 6pm (or did) and 1 pm on Saturdays. Due to the crisis we considered a potion in Germany and I commented to my wife about not being sure if I could adjust to weekends being sooooo dead. And I don't mean big stores not open on Sundays, but EVERYTHING closed, especially on a long weekend!!!!
