No surprise to most of you—emotions can change your "normalized" intuition. In the moment, if you're angry or PO'd, your gut will give you an answer for sure (but perhaps not the answer that your gut normally would).
Best practice—in the moment, step back and ask yourself, and given that most decisions aren't life-or-death therefore allowing you some time to contemplate and deliberate, "is this the very best time to make this call?"
