I used to work for the sewer department of the city in which I live. I'll go back to that job if necessary if King DT wishes.
Obviously, I can deal with ALL sorts of sh*t!
(I literally got sh*t on once - - I was working at bottom of a manhole and a private lateral line pipe was at the top of hole, about three feet above me - and someone had flushed their toilet, it came out the pipe and it all landed on my head and shoulders and back.)
I'm not in Mexico City. I didn't have quite that kind of experiences. Crazy how that video seemed to show the contamination between storm (rainwater/draining off the streets) and sewer (toilet/etc.) lines.
But the day I got flushed on, my partner and I laughed a lot and it was our last work site for the day and he drove me home early so I could shower. :)
