In a UAT meeting with representatives of our project partners,

The account executive, who set up the project, said to my PM in front of everyone just before the test started: "I hope your system won't fail, because everyone here will be watching"

My PM: "No it won't. But in that case, I believe it's your fault for setting an unrealistic deadline without consulting us, the development team, first"

All the representatives, being also developers from multiple companies, proceeded to stare at her with disgust.
