This is kind of old news and was happening last year. And I’m thinking with the massively more infectious Delta variant, the question of whether or not the ventilation is adequate to prevent infection is a pretty solid “no”. Nobody should be taking off their masks indoors. And nobody should be relying on cloth or surgical masks on their own. You need respirator grade masks, or, in a pinch a tight fitting cloth mask over a surgical mask that has good filtration.
