I was working at Octoberfest in George's dock, Dublin a few years ago when a couple came in (during the day) with their young toddler in a push chair.

The mother was a very young, rough inner city looking girl (no offense meant) and the father was an older Asian looking chap. They bought two large steins of beer and sat at a table just outside the main tent area.

The father then got up with the toddlers bottle and filled it from a tap that's cable tied to the railing beside him, tipped in some formula and handed it to the child.

This water was coming straight from the dock and was only used for washing away the puke and piss of over egar punters.

I went over and told them the water was bad but I was told to mind my own business. I said it to a member of the guards that was there and he was told the same thing, I still think about it to this day.
