Years ago when I worked at a K-Mart we had a problem with people in the surrounding neighborhood leaving their trash by our store's Dumpster. Every week there'd be random crap strewn all around it - household garbage, old appliances, etc. because they were too lazy to haul their crap to the dump themselves.
Anyway, one Monday morning the manager tells me that someone had left a couple of trash barrels by the dumpster (yet again!) and told me to go out there, empty them and get rid of them. It was a beastly hot summer day and the trash barrels in question were filled to the rim with what looked like the remnants of somebody's summer Barbecue - maggoty meat, filthy paper plates and cups, rotten fruit, etc. As the barrels had been cookin' in the summer heat for some time, the STENCH coming off this stuff was unbelievable. As soon as I got a whiff of it I lost my breakfast. Haha.
Somehow I managed to get the stuff into the dumpster (barrels and all), though it took me a while, and I was nauseous for the rest of the day. When I was done I asked the manager "Please don't ever make me do that again..."
