My girlfriend put frozen chicken in the sink in the morning, around 8am. Her car broke down and I had to try to jump start it and it didn't work. So I drove her to work. Before she knew her car wouldn't start, she wrote a note asking me to put the chicken in the fridge. I forgot. So now it is 7:27PM and I just put it away. It started frozen, but then probably totally thawed by noon. So it sat out for seven and a half hours after thawing, maybe more.
