Right before the lights went down at a recent preview screening of Trolls World Tour in Hong Kong, an usher screamed at a couple who decided not to sit in their assigned seats. “You have to sit exactly where your ticket says!” he yelled. “We’re doing this for a reason!”

The reason, of course, was to prevent an already jittery audience from becoming even more uncomfortable amidst the presence of the coronavirus. Signs of increased vigilance had already included mandatory use of hand sanitizer at the front entrance, a handheld temperature check upon ticket entry, quarantine wristband checks (people arriving in Hong Kong must wear tracking bracelets for 2 weeks or face jail time) and the requirement that patrons as well as staff members wear face masks at all times.
