Angry, loud and officious staff.
No one was around, so I attempted to load my donated goods into a bin myself. After several minutes, a very loud, very angry employee ran towards me, invaded my personal space, and spent several minutes chewing me out for touching Goodwill property without permission.
You don't normally expect to be treated the way I was just treated outside of receiving a speeding ticket.
I didn't feel physically threatened, but I'm a pretty big guy. I imagine a woman in that same position might have felt differently.
Avoid this donation center.
