The young barista at the Starbucks in a Kroger on Wednesday morning was on the phone with her grandma when I walked up to the counter, and said an unapologetic, unselfconscious "I love you a lot, Grandma" getting off the phone before helping me.

Yes. Correct.

Also, as JLo1972 commented here, for mouse lines, cell lines, etc., supplied are required to keep them alive. And samples stored in liquid nitrogen need to not thaw. Etc.

Not to mention clinical trials, where patients are currently being treated.

Jesus Christ. If this extends to liquid nitrogen and mouse chow, hundreds of millions of dollars in reagents like cell lines and genetically engineered mouse models will just die and decades of work will be lost. This will be catastrophic.
