I always assume that people who whinge about masks - unless they have a very serious medical or mental health reason not to wear them - are also likely to be people who have had people round their houses and taken little notice of lockdowns. So best avoided!
Why do you assume that people who "whinge" about masks have had people round to their house? What is your logic for that?
Outside yes for the G7 lot, but some of photos show scenes that if a pub was allowing to happen would be in trouble with the local council if they found out.
There are indoors pics too and not a mask in sight.
Childish response.
The definition of "childish" im fairly sure isn't expecting those imposing rules on us to follow those same rules 
And you haven't had the experience of someone coughing/sneezing on youyet. When/if they do - particularly now - I'm betting you'd prefer they were wearing a mask to mitigate the amount of snotty, germy air that is blasted into your personal space. (You won't know if they're vaccinated or not, either
I've been almost 60 years on this planet and barring my own DC when they were small it's never happened yet. Maybe I'm just lucky, maybe people get sneezed and coughed on all the time but I must say I've never noticed it.
I'm assuming that all attendees of the G7 are fully vaccinated.)
Plenty people are fully vaccinated they still have to follow the rules our leaders don't have to bother themselves with
