One sign of lovable humans

At my work we have a sign above the urinals that reads: “Please refrain from throwing chewing gum in the urinal since this tend to block the piping”. And every time I go and use the facilities there are at least 3 or 4 discarded chewing gums in each urinal. To me this is a good sense of humour and a healthy sign that people won’t always comply within the “rules”. It might seem silly and juvenile, but I like it.
