I took 15 interior doors for donation to Habitat for Humanity Restore (Midland, TX). I checked in with the office, and the female staffer told me to drive around back and someone would help me unload. I waited 10 minutes in the back and no one came to help, so I unloaded the doors by myself. Just after unloading, the male staffer finally showed up but complained that I put them in the wrong place and he could not move them by himself. So I helped him move them. Soon after moving the last door, another female staffer told me they were not accepting interior hollow core doors. Both staffers turned and walked away with no offer to help me load. Moreover, I got no thank you. I'll never donate any items again to that place.
