All the etiquette in the world isn’t going to make bike parking areas appear.
Amsterdam has been bike friendly for decades, there aren’t any bike racks near any of the stores I regularly ride to. And when there are racks they tend to be behind the building or off to a side where long term parking would be a risk for theft.
I usually end up stashing my bike near the entrance and then hiding it behind grills or mowers outside at hardware stores. Or flower racks (or pumpkin piles this time of year) at the grocery store.
We need bike racks in visible convenient places. And more of them.
