I guess having lived the vast majority of my life with no mask, I still fight to remember to have it with me all the time. We each have a two layer mask that has a layer of activated charcoal in a pocket on the inside, and then the mask. That is used most of the time, and Mrs. Carrera washes them fairly often, and we replaced the activated charcoal pad.
I have a plain N95 surgical style mask in the glove compartment of the El Camino. The other day I took the 911 out to dinner and forgot my regular mask. I have a Michelin bandana-handkerchief thing they handed out at Parade one year. I keep in in the 911 just in case I needed it to wipe of my sweaty face at some event. It was folded and in the door pocket. So I made a old style Cowboy face mask. Those cowboys must all have little noses and small heads. I can just get it sort of tied on and my nose is smashed and uncomfortable. It was on long enough to get into the restaurant, and sit down.
The good news is evidently Covid only spreads if you are standing up. Once seated at the table it is OK to remove the mask so it must not spread when seated.
I guess I need to buy a good stock of face masks, and put a couple in each car.
Next up, "they" need to invent a foldable sealed mask we can carry in a wallet that is always with us.
