I have a fond memory of when my boss called me brilliant in a room of people. I had come up with an innovative way to double our matched funds from a particular foundation. Mind you, we all were in a bar. And the room was full, but only one other person was at our table and the rest were dancing. And this was after several rounds of beers and one round of tequila shooters. And this was to raise courage for the flaming sambuca shooters that were just coming.
So this may not have occured during a regular performance review, but I still count it!
