I think that whole "bother me and i'll take longer" thing is disgusting :/Next time i would take that as a red flag and cancel or just avoid buisness with the person until they grow up a bit.
Sorry you're going through this bro, and i hope you get your money/art ;3;

and in regards to the name thing, whats in a name yadda yadda yadda. But i certainly wouldnt commission someone named irapebabies or isteponcats. Theres only so much nonsense i can take, and im a pretty silly person :>
