PO: "Remember guys, protect your scope!"
.. moments later, after the PO meeting..
PO: "I want you to do user story x but I want it changed this way"
me: "Ok"
*pling* notification: PO changed jira story
*I work on it for a few hours*
me: "Is this what you wanted?"
PO: "Yeah, actually I made up my mind. I want you to implement it totally different and scrap what you added now"
me: "Thanks for wasting my time bro"
me: *codes*
.. a few hours later, mid-coding..
PO: "Uh, yeah, changed my mind. The way you did it now is ok, but I want something else added"
*3 iterations of the same crap later*

me: "Sigh, make up your minds!"
