Majority of retail continued throughout the "lock-down", but with an abundance of care taken in terms of keeping a 2m distance, limited number of customers in a shop (queue stretching out of stores is a common sight), and alcohol sanitizers everywhere.
The majority of businesses and institutions have reopened (schools and kindergardens being the first ones), and restaurants, café and cinemas have just recently opened (with appropriate restrictions).
What is interesting is that Sweden has seen the roughly the same level of economic contraction as Denmark, despite the vastly different policies.
