10 PM (after a very busy working day), CTO calls me and tells me: "We decided to hand in the new version to [random client] one week earlier, so they can test it."
Me: "I don't think is a good idea, the app is still unstable, we started working in it yesterday, it *will* crash"
CTO: "Don't you worry, at least they know we are working on it"
20 minutes later
CTO: "WTF why did you make my app crash?! I can't send this to a client!"

Told you. That is why that code is on develop and not on master.
