In general I agree, but this has been complicated here the last few months due to Covid-19. Stores have both limited hours and developed senior only hours. There were also sometimes people queueing up early to buy “scarce” goods like TP when the store opens. If you go to a store at open you might get turned away, find the store doesn’t open at the posted hours, or find a small crowd.
I’ve been going around 11 these months. Stores are open. Senior hours are over. Working people aren’t on lunch yet. Non-working people have generally not gotten out. And usually I see employees restocking goods.
