What did my worst job entail?

One of my worst jobs was working as a kitchen porter and glass collector at a struggling restaurant. The previous owners had left the kitchen in a disgusting state, and one particularly horrifying task was cleaning out a big metal drum used to cook or smoke ducks. The drum had never been cleaned, and there was a 20 to 30 centimeter layer of brown, sticky residue at the bottom. It was a long and disgusting day of cleaning, and at the end of it, I was completely covered in the sticky goo.
