Sure. We are always germy. But if you feel explicitly under the weather and you have to go out to the store to pick up something, it would be great if you wore a mask - even if it isn't covid times.
I've never done that. I've always just gone to the store. I didn't even really think about it, like of course I'm not going to be wiping my nose and touching things, but I'm also not sanitizing my hands the instant I walk into a grocery story - something I now do every single time.
I do wonder what the effect would be of just having sick people wear masks when they go out?
