You weren't out of line at all. If the "ditz" at the other end of the line had a brain she would have been more cordial and "asked"- not implied. She has to remember she's asking for your help, if you're tapped out - fine - end of story, thank you. But to be rude to you - fuck her! No excuses, I don't care if she's had a bad day - she caused it and she's doing a big injustice for the cause. I give hundreds $ to charities but if they cop an attitude or their rep does - oh well it's their loss. Blow it off bro, they'll figure it out in time that that particular rep is worthless and is doing more damage than good for their cause. Some people lose perspective of what they're trying to acheive. If it was a scammer, then better yet - screw them!
