Emergency Alert system used mid afternoon in CA Wife anon,shopping and waiting in line received " covid update" along with everybody in the store@ the same time.  It basically said " you need to go home" . Right around lunch time . She called to see if I got the same one which I did not( no software updates done on my phone since 2012)  I checked with my cell phone devoted friends  and yes they had gotten the notice as well. Yep next step going forward, LA city app using Bluetooth/ GPS and broadcasting / monitoring positive tests and Alerting any Bluetooth device in range is already being rolled out.  ( honestly don't think it will catch on though ! )  So literally everyone in the store who had a phone had it go off @ the same time. Freaked her out!  I said " gee honey, did you think I was full of crap this whole time?  Bwahaha
