I was about to raise my hand to knock on the door when one of the women inside opened it, looked at me, and said in what came off as a very nasty tone of voice:
"We don't take clothes until eleven. And we don't take them like that *looks disdainfully at large bag on my shoulder*"
I was too stunned to really say anything, so I must've looked pretty silly for a few seconds there. She added "thank you" as an afterthought, and I booked it outta there and down the street and donated my clothes at the next shop I came to. Really, now.
