*get task assigned to me*

*complete task*

*get new task changing everything I did in the previous task*

Me: "Why is this getting completely changed? It meets the specs you sent."

PM: "Well, they took a while to approve the concept so I assumed it would be the same as the one on their current site. But now they want something different. Just change it."

ARE YOU FUCKING KIDDING ME. WHAT IN THE ACTUAL FUCK IS THE POINT OF SENDING FOR APPROVAL IF YOU ARE NOT GOING TO WAIT FOR THE APPROVAL?!
