Let’s see…
Hotel rooms, hotel related restaurants, conferences , meeting rooms, concerts, graduation ceremonies, massed meetings for trade unions or big companies etc, religious services, stadium tours,
Senior supporters association closed shop meetings
social functions, weddings, charity dinners, Christmas parties, school prom nights,
I could go on.
Most of which happen at our and other stadiums on a regular basis.
Do you live in the real world?
Which already happen... So are totally irrelevant to this thread.
