There have been reports of hoarding.
I saw it for myself. Big group around the local pharmacy, which was closed, on the day Trump first talked about it at the presser. Talking among themselves, but when they saw me reading the sign in the window, a sign telling people to call a phone number, they dispersed, presumably because they thought I was eavesdropping (I wasn’t but when they dispersed I was suspicious!). I live in a densely populated upscale neighborhood with lots of doctors.
