Singing, where everyone is singing enmass apparently expels a lot of vapour in droplets according to Prof Baker. Plus a lot of the people would know one another etc. Also very closely packed in rows. Whereas a dinner event maybe more spaced out with tables. Nightclubs not everyone knows one another, maybe a lot of people heavy breathing.
The levels IMO really needed adjusting months ago when Delta became such a threat.
Sure, I just felt the original comment was pretty unfair.
