The existing restriction on number of people in shops say max 1 on 15 m2.
With the increase of infections gov is considering "drastic measures" by reducing the limit to 1 person on 10 m2, but that might be seen as "too liberal" so 1 on 7 m2 is more likely.
This was later corrected on the website that first posted this nonsense - but comments from angry readers still refer to these 1/7 values. Unsure if that was journalist, or the original source in gov.
