I get the feeling behind this, but it's also silly. Either you're outdoors and the risk is already pretty low, or you're indoors, and 30s of exposure won't be a big deal, especially when it's not like everyone is wearing N95 respirators and aerosols are a bigger concern than we used to think.
It spreads so poorly outdoors (this has been abundantly documented), especially if your exposure to someone is brief, that the main reason is a combination of virtue signaling, hygiene theater, and because it makes you feel safer.
Or, because you feel it's a conservative decision which is respectful of others. I'm not worried about incidental exposure from passing someone on the sidewalk, but I can only make that decision for myself, so I either mask up or get out of the way.
Etiquette is a rational enough reason.
I’m back in SF now and everybody is wearing the mask. Everybody. The adults, the children, Even the vaccinated people. Yesterday the waiter asked me if we could put back our mask so she could hand us our plate.
Country of extremes. I feel like there’s no going back to normal eventhough I’m fully vaccinated.
