I think dealing well with frustration is a personality trait. In a large enough company, I really believe you should let people specialize in dealing with the client. To do it well requires a skill-set and personality that are at odds with other types of work. I get very frustrated with things that don't work, don't respond usefully, that make me waste time and that can't be automated (to require less supervision). That frustration builds up and drives me to improve things, great for machines but almost always self-defeating around people.
