I frequently go to stores that are open at the convenience of the owner. Often this is out in the country, but there's even one storefront near me in NYC that proudly says, "open by appointment and by luck". You quickly get used to the human-scale patterns. Once when I was in Munich I needed medicine on a Sunday. Despite the pharmacy's posted hours stating it would be closed, I was somehow able to raise the pharmacist and get the medicine I needed. I was very grateful that day to have a human in the loop. I hardly think store opening hours are a good argument for the "absolute necessity" of supreme rule of the wall clock.
