So I wasn't laughing at the suggestions that Chic-fil-A do the testing, eg, have those people standing in front taking information with their notepads, and automatic email reminder to get 2nd shot etc. But,t that's an information system that isn't developed yet not so simple.

So, they have people fill out paper forms...which get compiled later? Give everyone a card saying get 2nd shot in three weeks? I can't see any record keeping up in real time. Just give the shot and trust the people to come back in several weeks because its in their own best interest.

My real argument was it really didn't matter much who you gave it too first, eg, fast food workers and checkout clerks because they're exposed to the most amount of people is as good as anything else.
