Ok, here’s a short non-scientific study of mask wearing, as experienced on a mid-morning London Overground train, from Clapham Junction to Willesden Junction, today
(Bear in mind that at this time on a weekday, the majority of passengers are bound for the Westfield mall at Shepherds Bush, where face coverings are also mandatory)
From my own observations, looking around on the platform and at passengers alighting or boarding at 4 intermediate stations, I noted the following numbers:
No mask: 12 (including 1 member of LO staff, and myself)
No mask, drinking beverage for entire journey 21-minute journey: 1
Worn under chin: 13
Worn hanging off ear: 1
Worn over mouth only: 17
Held on face with hand (not using ear loops!) 1
Worn correctly: 42
As I said, not scientific. But I saw under 50% of passengers wearing the covering in the correct manner, and 13.8% non-wearing
One thing that made my morning was that a young Asian woman with glasses, who was also bare-faced, but looked decidedly nervous, saw me and seemed to deliberately sit opposite me (the seating is longitudinal) - perhaps for reassurance? When she caught my eye, she gave a shy but beautiful smile... which of course I would not have seen if she was masked !
