Time out

A day off and a beautiful day. I went for an aimless walk and ended up having lunch on a near-empty beer garden before walking home via Clissold Park.
Several groups of more than six apparent. One of which is in extras.
I had to pop in the supermarket on my way home. 
While I queued to pay in an aisle clearly marked out in 2m distances, two older teenage girls stood within a foot of me chatting happily about not being made to wear a mask by the security guard. 
I turned and told them if they were not wearing masks then the considerate thing to do would be not to stand within 1 ft of me. They consented to move about 3 ft away from me. 
My first challenge since this whole pandemic began. My patience with the whole thing and lack of consideration of others is beginning to wear thin.
