I picked up a fridge one time from a call that came from one of my moms friends relatives. When I got there he actually had 2 of them waiting outside for me. As we were loading them I could smell the one was reeeeeeeal bad but i didnt' say anything because it still scraps out smelly or not. And, he called me again after that to pick up something else. I figured that was more important than the smell.



Now, I'd say that leaving food items in one would be just plain rude. and inconsiderate.
