Me: We have a new research project for you. We need you to test these 2 new services, see how they will fit into the new application, look at alternatives if necessary etc. At the end we need you to write a report with your findings, showing how you would integrate them to achieve X, Y and Z, and how much it would cost each month.

Dev: sounds good, I'll come back to you when I have it.

*2 and a half weeks later*

Document paragraph 1: The new language translation service doesn't support the languages we need.

Document paragraph 2: Here's my proposal for integrating the new language translation service.

*review*

Me: So I had a look at the doc and it says it doesn't support the languages.

Dev: yeah unfortunately not.

Me: Ok, so when you discovered that, why didn't you look for an alternative? Or come back to me and say it's not going to work.

Dev: I dunno, I thought you'd want to see the rest of the research first.

Me: ... not if we know for 100% undeniable fact that it will never function.

Dev: Ah ok, I didn't think of that. I'll do that next time, don't worry.

... aw how sweet, he thinks there will be a next time. Poor guy.
