I've had to deal with difficult clients before. Some are quite demanding, some just get angry, others, they just don't quite understand what's going on as far as all the facets. So I try to talk to them, find out what they're really upset about, and then we discuss that. And I get them to open up, understand, and then we go from there trying to find a solution. Because that's all they really want, is a solution to their problem.
