It seems like some people say, "WHOA! I gotta take a shit real bad! Better hurry to get to the pet store or I'll crap my pants!"
We have a very basic staff bathroom. We do not like people going through the store room to get to it, because they usually take merchandise with them which they can easily steal, and that's where we have to leave our unguarded coats and purses that hold our meager belongings.
I don't mind when a old lady with bladder control issues asks to use it. But in most cases, I try to discourage custys, saying the toilet doesn't work well, which is true enough, and that they should go next door to Poopnera, which has a far nicer public restroom. But every now and then, the spineless manager lets someone use it.
One day it was a boy of about 12. As he left the bathroom, he greeted me with a big smile, and waved and called out cheerfully, "Thank you so much!"
I thought, what a nice boy with manners, more rare than a purple unicorn.
I went into the bathroom, and the toilet bowl was densely filled with what looked to be a family size package of kielbasa, a two inch diameter log of compact shit he did not even attempt to flush. Not only did the toilet clog and overflow when we flushed it, but we had to pull out what we could, and break it up what we had to with a coat hanger.
