It's Holy Week this week (the week before Easter starts) and every day there is a service in each parish. UK, Roman Catholic churches. You have to book online to reserve a place. A quick look at a few parishes in an area for big and small churches shows that all the services for each day of the week and weekend are booked out in advance.
Obviously the numbers able to fit in the churches are capped because of Coronavirus, but it appears as if there are more people who are wanting to attend than can. What I can say with some confidence is that there is at the very least more demand than the capacity.
