爆米花危机（朗读）

Now playing at a theater near you: a suspense drama over whether there will be enough popcorn for the summer moviegoing season.

The plot was palpable at CinemaCon, an annual convention for movie-theater operators this spring. The Las Vegas event floor had a festive vibe, coming after two years of pandemic-darkened screens. A-list vendors such as Mars Wrigley (M&M’s, Snickers, Twix) hawked sugary wares near makers of polyester theater-worker vests and seating experts modeling the latest in auditorium recliners.

But there was also a foreboding. Theaters are finding workers harder to hire, and inflation is hitting costs. Perhaps most chilling, supply-chain issues are foreshadowing shortages behind the concession stand, a crucial profit driver for theaters.
