[Question] How do you use face masks?

I did buy face masks a while ago, be­cause other ra­tio­nal­ists recom­mended wear­ing them.

The list time I had a flu and went to the doc­tors office I wore a face mask, the re­cep­tion­ist then told me to take it off while sit­ting in the wait­ing room.

While I do think I have a bet­ter idea then that re­cep­tion­ist, I still don’t know much. It’s easy to have su­per­sti­tions about how to use face masks cor­rectly. If I want to go for max­i­mum benefit with min­i­mum has­sle, what’s worth know­ing? When do I throw masks away?
