An old client of mine was quite famous for his impossible requests.
Here are three of the best:
Once, when deciding the size of a logo that would appear on an animated graphic destined for TV, he just took his phone, stuck it on the screen, took a measurement and said:
Client: There, just make it one-and-a-half phones big.
He would frequently point at a screen, TV, or piece of paper and make this insane demand:
Client: This black part here should be shinier!
I still don’t know what he meant.
This one is my favorite, though. He was also obsessed by symmetry. His meeting room had a table with a huge triangle inscribed on it, and it drove him CRAZY that four people were sat around it. After wasting a bunch of time trying to “solve” this “problem”:
Client: Is it possible to make a triangle with four corners?
He was not joking.
