Assume no mixing of households though? I was in the pub the other night and 4 lads walked in who clearly weren’t from the same house. Was just wondering if that’s just our pub being slack or widespread.
It is impossible to know if people are from the same household or not. There could easily be 4 people sharing a house as well as the less usual 70 people from a circus counting as the same household. The pub can't enforce anything.
