I'm seriously considering going to Richmond, CA Costco Thursday morning 8-9PM when they have 60+ hour. They require masks, but don't know if they enforce... I have a feeling they do, well, at least not letting you in if you're not wearing one. After all, there's no entry without a membership card. If I don't like what's going on, I can leave, not even buying anything. That's exactly what I did on March 12, things were starting to heat up (it was SIP starting March 16). The checkout lines were 50-70+ feet long and people standing right next to each other... I just walked out empty handed (I only had one item, it was hard to find the things I really wanted, panic was setting in). Now, I'm told, they have spots marked on the floor where you're supposed to stand. If I go, it will be my first time indoors with anyone since March! I'll wear an N95 if I go, maybe a face shield and gloves. If people are talking, I figure to go in the other direction! I may not go. The case/day rate is around 3x what it was a month ago and the positivity rate around here is probably 6-7%.
