I live in London.As of at least last week,one can't buy masks or hand sanitizers. This is a country of 60M people.Yet, when I commute to work,I see probably 1-2 people with mask,which makes it about 0.1% of all people I see on daily basis.So my question is,who has all the masks and who's wearing them?
