And the owner was busy suing his sons to get back the companies he gave them because they were now turning a profit. No, not the same as Erika's, but pretty surreal nonetheless. You should have seen the source files for their animated ad banners, though. Many times I find it challenging to balance client wants and needs over the production of a polished final product. Too often timelines cramp the style of good process, but I guess the contractor has to compromise with the client to produce the best product for both parties.
Agencies have a duty of care to clients.
And a large part of this is warning them when they are about to do something stupid. If you do something which you know to be wrong, and it returns to bite the client, they will blame you for not warning them even if they demanded that you do it in the first place . At best, this could damage your ongoing rapport with the client. At worst, it could end up in the courts. You may still end up having to do the stupid thing, but by raising it as an issue along with an assessment of the likely impacts, and getting them to assume the responsibility for it, you have fulfilled that duty.
