I think it's trying to take account of people who may be shielding within their own household? so they could go for a solo run but could go and play golf or hike with a member of their household but still stay 2 meters apart?
Nah. still doesn't make sense, if they were self isolating within their own home then what difference does it make whether the 2nd person is from the same household or not?
More bonkers stuff that has no basis in science - it's all now either political or a finger in the air job.
What difference is there between going to a park and buying takeaway food from a vendor and sitting eating it on a bench, 2m from the next bench, and sitting on a bench in a beer garden 2m away from someone else, eating or drinking supplies from the pub?
I'm really shocked at the way some businesses have been treated differently from others where the same risk applies. What about shops in shopping centres too, most of which are large and airy, so shops on the outside of the complex that have a door to the outside can open but if they are further in the centre they can't? What about if they are near the entrance? Is it to stop queues being next to each other? What about a row of shops outside trying to keep their queues apart?
What they actually need is proper guidance such as X customers per square foot of shop space, aisles need to be x wide, Perspex screens need to be installed at tills, no more than x staff restocking shelves when open and Y when closed. Then they can decide if they are able to open or not.
