In my entire life, no one has directly sneezed on me except for my own kids when they were little. I'd rather they cover with their elbow than us all wear a mask.

If they are covid infectious, I've already inhaled their particles before they sneezed if we were both wearing surgical masks. See that study I referenced.

You should watch some of those clever (thermal?) imaging videos of what happens when people sneeze when using various kinds of coverings (or none at all).

The aerosol spray from even an elbow-covered sneezed is something to behold.
