Here's one that's only tangentially related.
For over a year, I worked in a Burger King. It was okay work, and the people were generally decent. This restaurant had an indoor playground, with fake grass carpetting.
Fairly often, I'd be called out to perform a particular cleanup task. Y'see, parents often brought their kids in, made them eat
first,
then sent them to play. You might see where I'm going with this,
but it's better than that.
The playground, being indoors, didn't have major playground pieces. One thing it
did have was a merry-go-round of the sort that you have to push yourself. Fast.
So I'd be called out to clean up the circle of puke around this bit of equipment. Occasionally, I'd be asked by a parent, after she (almost always "she") finished apologizing, how I could stand to do it. I just told her/them that it happened all the time and I'd pretty much gotten used to it.
Last time I went to that restaurant, they'd closed the playground. Liability issues, I assume.
