I felt so terrible once after staying a few nights for work- I was freshly out of college and had a government training
We all passed our exam and had happy hour wine. My colleagues didn't realize I hadn't really drank much before, and I got shit faced on wine so bad that I needed the toilet and to throw up at the same time, but had no way to clean it and it wouldn't drain from the bathtub
I then had to work whilst probably having alcohol poisoning (couldn't retain any sips of water without needing to vomit 12h later) and needed to rush over to the office
I seriously felt so so terrible that someone needed to clean it, and I always try to leave the rooms the way I entered them every time I stay anywhere henceforth
