You are much more brave than I am.
All I did yesterday was to go in through the out door and out through the in door, talk on my phone all throughout the store with my mask lowered for it, and refuse to wait in line at another store to be let in per their 50% capacity thing. They had plenty of room and people were not keeping six feet apart anyway.
When I grocery shop its in the wee hours of the morning hardly anyone else there, you can go in the door with the face diaper and once inside it tends to slip off, ya know.
