Oh ! I like your idea to donate to the women's shelter. That is certainly the worthiest of causes.
I was just thinking those shops depend on people's clothing for their very existence and they are getting them cheap to boot. Even if they don't end up liking what was brought in by someone, you'd think they would be ever so thankful that people keep bringing them. Who knows, that person might have friends with clothes the store would like, but when they are rude, who is going to recommend them to their friends? Makes no sense for the business they are in.
