Tourists Defecating in Bathtub

https://youtu.be/WnrwupJR6JU?si=4nhOdXhwFaidc1af

I knew about the other heinous behavior by certain tourists mentioned in the media, but I had NO idea about hotel patrons defecating in their hotel room’s bathtub! It’s at 2:13 of the video. Aside from the obviously pungent, foul odor, that could have wreaked havoc on the plumbing system. Lots of plumbing systems, particularly the older, traditional hotels and homes here cannot handle such heavy material running through the pipes. Let me know your thoughts on this one and anything else that has shocked you.
