I think you're posting on the wrong thread. You need the
'most over the top restrictions introduced' thread.
But having said that, I am very curious. Is it any three from six at a time, or are you supposed to 'bubble' into two groups of three which never mix? If three are in, and person four wants a cuppa, is he allowed to go in and make it while person one is in the loo? Or would person two be allowed to make it and leave it outside the door? If person three leaves, are persons one and two required to disinfect the kitchen with bleach before person five enters? Do you have any restrictions about other rooms, or just the kitchen? Would it be ok for the fourth person to stand just outside the (open) kitchen door so they could join in the conversation? Has your rent been reduced to reflect the fact that you only have access to a kitchen for 50% of the time?
