Yes, they have a 7pm curtain on Tuesdays and Thursdays. The evening curtain is at 8pm on Wednesdays to allow for extra time between the matinee and evening performances. Earlier in the run, they had all evening performances beginning at 8pm, but they've been on their current schedule since the show opened.
Either way, though, it's up to the ticket-buyer to decide what is acceptable for themselves. If they buy tickets to an 8pm performance on a weeknight, that's their choice. The show doesn't seem to have had trouble selling tickets to those weeknight performances.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
