he sounds like an idiot.

if you're asking him to do things he considers 'mistakes' - like asking to use hot pink, or a marquee or something he considers a bad idea, as a responsible designer he should confront you abut the issue when it presents itself and come to a solution that resolves it, not just do it anyways because that's what you asked for. that's why people pay designers instead of trying to do it themselves.

morons like this ruin it for the rest of us because it paints this image that we're just production slaves with no creativity of our own.

charging another $200 isn't uncommon, or greasy activity. it makes sense when you break it down - the deal was $400 for this amount of work and all the fixes he needed to do were outside the scope of the $400. however, going ahead with mistakes, that he knew about - means he knew he'd have to charge you again for fixing them, just because that was the scope of the $400 makes him an idiot. $80 to copy/paste some text is ridiculous too.

there's 2 schools of thought on billing: fixed price like salary, or hourly. if he's providing a fixed quote, he should be factoring in mishaps like revisions, copy updates and things like that into his price from the beginning. that's how salary works, sometimes you get paid for doing next to nothing, sometimes you work 70 hours that week. hourly, he should be giving an estimation - not a fixed quote - and provide records when he sends the bill.
