My coworker got the Covid. This mf been out sick, came back 1 day, and found out he tested positive later on in the day. I talked to that mf for a total of 3 minutes yesterday, and gave him an elbow bump. Now I'm quarantined. I'm mainly pissed at my supervisor for letting him come back to work when he been out sick. 

South Korea had ten minute wait times for testing and next day results.
