kathygry – Depending on what movie theater you go to, your ticket stub may also be your receipt. Since you didn't name the MSC, would you mind naming the movie theater you shopped? I've shopped both AMC and Regal theaters, so I can look into my records with what was given to me at those theaters.
Anyways, with all movie theater shops I've done, the ticket stubs themselves and proof of purchase at the concessions were the make-or-break documents for the shops.
If you haven't already, I'd contact your scheduler informing them of this. I'd still proceed and finish the assignment. From my experience, these movie theater shops aren't extensive anyways.
