It would only take one bout of food poisoning for him to be happy with the fridge... just sayin'!

I used to work in a commercial kitchen and this is what I learned:
food can be left out (at room temp) for 4 hours safely. But this is the TOTAL, so if you had meat that was out for an hour, then you cooked it, it could only sit out for another 3 hours.
you should put things in the fridge as soon as they are cool enough that they won't bring the temperature of the fridge up (ie so not when they are boiling hot, but no need to wait til they are cold either).
cling wrap is pretty toxic and I wouldn't want to eat food that had been touching it when it was hot
