It's more likely that they had a friend over to help them learn about an instant pot, thought they were being safe but took their mask off to have some coffee, got a bit closer than 6 feet in a small kitchen, and stayed for 90 minutes with no air flow. But they didn't think it was a big deal because it was their friend...(I'm not trying to pick on Bisous's mom, but a lot of people make that mistake that familiarity = safety, and it isn't true)
But still, I know several people who got it despite very good mask wearing and don't know where they got it.
