Some movie theaters show an attention getting public service announcement about talking, texting, phones, etc prior to each showing in each of the theaters. I haven't seen one of these at The Villages three locations. I wonder if that might help! Maybe something like a 30 second movie short that uses a "yes, this means you" approach and respectfully but firmly delivers a STFU message, if you'll pardon my directness. It could be done with some humor, but needs to make the point in a strong way. What do you think? Worth a try?
