He might be legit, but he's not the friendliest caper out there.
Just be warned, I got a rude reply for asking a question he could have said "no" to. No telling what his angry/rude behavior will do if he gets mad while getting your cape. Just saying, watch out for this guy.
Edit: I do understand that I should have read his thread more carefully, but honestly, if a paying customer asked me a question like that, and I knowingly put it in my thread in obvious text, what would be the respectful thing to do? Ask if they are retarded? No. I was wrong in not reading the post but this guy could have handled his anger better.
