Thewre are too many entrances and exits to keep an accurate count, only letting in one person when someone else leaves. In the old days when you walked through a casino, how many empty, unopened tables, closed pits, and vacant slot machines did you see? Sure, a busy casino was crowded, with people wandering around, and on a Saturday night business was brisk. Plus, I wonder if '25% capacity' means one-quarter of every available seat.
