Director and screenwriter Adrienne Shelley may or may not have drawn on life experience when writing her latest play, Waitress. She did, however, call on her real contacts when she asked WET, the not-for-profit theater production company that supports women in the arts, to help stage the show.

That was last week. Fast-forward to tonight (and tonight only): There will be a reading of Shelley’s script at the East 13th Street Theater. The plot: a quirky, romantic story of a waitress who can dish it out everywhere. Except, that is, at home. The conflict: She hates her husband and she wants out, but she just found out she’s pregnant. The supporting players: pie-serving sidekicks and a nebbishy gynecologist.

Waitress stars Paul Rudd, Gretchen Mol, and possibly a certain commedienne whose name we’ve been asked not to reveal (but whose initials are A.S.). There’s going to be an after-party, so be sure to tip your caterwaiters nicely.

Hoping for seconds? You’ll have to talk to the chefs.

Reading of Adrienne Shelley’s Waitress, 6 p.m., at East 13th Street Theater, 136 East 13th Street, between Third and Fourth Avenues (212-396-4280). Tickets are free, but the theater is small. Accommodations are first come, first served, and priority is given to those who sign up. For more information and to put yourself on the guest list, go to wetweb.org.
