When your "product owner" just doesn't listen...

Skype conversation:

PO: What format will the dates need to be in for the csv file upload?
Me: Just tell them YYYY-MM-DD
PO: ok

Two weeks later...

PO: there is a bug in the csv file upload! The dates aren't being picked up
Me: ok will have a look, send me through an example date the are using
PO: ok, example date 12/03/1990

FFS! 😡
