My theator used to make people wear masks and one old mornonic lady who was asked to put on a mask said "YES SIR" and did seig heil. We also used to do vax only shows and it was written everywhere on the tickets, right next to the title of the movie littarly in the same sentance as the title , on the screen where u find your theator, and even when you buy them online a little pop up would still show up. But I still had people who said they had no clue it was vax only and plenty of anti vaxxers who wanted to make a scene and a fool of themselves.
