This ENFURIATED me for some reason.

So I was buying a GT puffwump bc why not, and I was telling my offer and someone runs up asking for an angelic for their bestie, i tell them go away and the gt seller say i "i dont trade with rude people". THIS MAKES ME SUPER MAD FOR SOME REASON! LIKE SAYING GO AWAY WHEN TRYING TO TALK TO SOMEONE IS RUDE? I KINDA GET IT BUT
