It probably did, but they probably got seats on the aisle.
And, you know, it used to be so common for people to arrive late.
There are people nowadays who defends noisy audiences, people eating during a show, and various kinds of audience behavior that some of us find troubling and distracting, etc., and yet it seems to me — perhaps my perception is wrong — that some of those also are among the ones most adamant that once a show starts, no one should be seated until intermission. (This never occurred to me before.) These people often cite other cultures and how the standards for audience behavior that many of us grew up with is a 20th-century change, that audiences used to be much rowdier, but arriving late or even in the middle of the show is similarly something that until fairly recently was not frowned upon in the way that it is now.
