Client comes in with paper brochure:
"It must look exctly like this."
Brochure is hideous, this job ain't going on my CV but client isn't paying enough for anything better so I go ahead and do it exactly like the brochure same colours, same font, same pictures - everything.
Present the job to the client. Client looks unhappy so I ask what's the matter?
Client:"Well I asked for it to be exactly like the brochure"
Me:"I haven't changed a thing, it's just like it"
Client:"Yeah but it's not A4"
Me(inside my head):"?&%#¤!"
Me(outside my head):"I'll see what I can do"
