You've changed your tune AOG. Your words...
// I think that the large stores should close all day Sunday, if people do not have enough time to shop six days of the week, tough.
Nothing to do with religion, just setting one day out of seven as a 'special' day, a day when all the family can be together.
At one time shops were not only closed on a Sunday but also half day on Wednesday, we managed quite adequately then.
Apart from all this, think of the small corner shop, they would lose that convenience Sunday trade, the only day that they get one over the huge greedy supermarket conglomerates`. //
