We've all had the experience of dealing with unreasonable people. It's not just designers who have 'clients from hell', but it's designers who've built an homage to client horror stories with clientsfromhell.com.
I'll be the first to admit - I had more than one sympathetic laugh as I clicked through the backstories.
At the same time, I grew more and more uncomfortable with what I was reading. Not that I think the site's inappropriate in any way, we all need a place to vent and a sympathetic ear to commiserate. I'm certainly not engaging in some PC tsk tsking about the poor treatment of clients at the hands of merciless designers.
Instead, as I read through the site, I came to realise that for many of the authors their war stories represented their own failures as businesspeople rather than that of their clients.
