Some clients are a real patience test.

Client:
"I want to be able to edit every detail on every page of the whole website"

After site is coded, and admin page is available for page edits, they send requests like:
"please update the text on page x"

Typical client syndrome...

I recently tried clarifying what values should only be editable by admins on this certain view, and the final response was literally "only admins should be able to edit it, but it would be nice if others could do it themselves as well".

Still an easy choice. There are two phrases that will void anything that follows it: "wouldn't it be cool if-", and "it would be nice if-".

I have that all the time.
