I recently had a liquid waste truck come to take away a vat that I nicknamed my witches brew - it was a 700L vat made up of expired wine making additives. I nearly vomited several times making up the vat (over the course of 1 day - it initially sounded fun but I realised very quickly how awful it would be, like extremely expired kombucha), but when that truck showed up and opened it's valves to start pumping.... oh my god, I will never forget it. It got into every space in the building for days. The gentleman operating the truck was so lovely, I felt so awful that I literally RAN away dry retching. Vomited half way down the warehouse.
