One time, also playing tired, I swear after losing a hand and quickly putting my next bet out, the took my newly placed bet on the same hand... I wasn't even 80% sure though considering how tired and aggravated I was. So I just kept playing and losing until I fianlly decided to leave. I learned that night to never play tired or hungry, and I also never get aggravated playing anymore because I understand how much of a monster variance can be.
