In the afternoon you will usually see a handful of people waiting to pick up a package at HEMA (official website, or check out the English Wikipedia page). It sells housewares and clothes, mostly made under their own label.
Under the current corona measures you are allowed to pick up packages at non-essential stores, although later in the week you will also be able to make an appointment to shop at a non-essential store. The rules are pretty strict, though; only two customers at a time per floor which is not helpful for large stores.
As you can see a few people are waiting for a package in this photo. Technically the pickup point needs to be outside, but it is actually just inside the first of two sets of automatic doors. If you look closely you can just barely see the white cart with three shelves and a blue bag – there is a customer inside picking up her order. And at least this way you don’t get rained on while you are paying for your order!
