Ask How do you handle client feedback you strongly disagree with?

[Brendan]

It can be very painful when you spend hours on a project only for the client to ask for changes that make the work look bad. You want to give them what they want, but you also want the work to remain good. I usually try to explain my professional reasons to them before making any changes. How do you usually respond to a client when their suggestions go against your professional knowledge and experience?
