A woman in the audience started grumbling around 30 minutes into a recent performance of “Staff Meal” at Playwrights Horizons in Manhattan. “What is this play about?” she hissed. A few uncomfortable seconds after she stood up and repeated her gripe for everyone to hear, it was clear that she was part of the show, which opened on Sunday.

The disgruntled audience member, played with relatable side-eye by Stephanie Berry, goes on to summarize the setup so far: Two strangers buried behind their laptops, Ben (Greg Keller) and Mina (Susannah Flood), strike up an awkward flirtation at an anodyne cafe. (“Singles in the city? I’ve kinda seen it before,” Berry’s heckler says.) They head to a restaurant where, just outside the kitchen, two veteran servers (Jess Barbagallo and Carmen M. Herlihy) are schooling a new waiter (Hampton Fluker) on his first day. (“Is this a play about restaurants or the people who work there?” the heckler asks.)

She goes on to bemoan the frivolity of “emerging writers” who keep “doodling on the walls” as the world burns. “Take a stand! Inspire action!” she pleads. She’s not alone in that sentiment.

Embedding self-conscious commentary about the worthiness of a new play, as the writer Abe Koogler does here, is an increasingly common trope. (Alexandra Tatarsky did it with unhinged gusto in “Sad Boys in Harpy Land,” presented at this theater in November.) Blame it on the world being in flames, and the playwrights who can’t help but notice.

But preemptively asking what the point is raises the expectation of a satisfactory answer, or at least one that responds to the provocation.

There is no one else to object when Berry’s character does what she has just harangued others for doing: relaying a bit of autobiography — she’s a widow and onetime aspiring dancer — that has no obvious plot significance. Back at the restaurant, the chef, Christina (Erin Markey), unveils her own surprising origins: a fantastical tale of class, opportunity and reinvention.
