Dear Prudie,
You are the go-to person for workplace bathroom etiquette, and I have a problem with a colleague of mine. Every time I use the bathroom and he is in a stall (I know it's him because we work in a small office), he flushes the toilet about seven times before he is done! Admittedly I am a bleeding-heart environmentalist, but this one really bugs me because we live in California, which is suffering from extreme drought. I think it is incredibly offensive to be wasting so much water. Is there any way I can bring this up? Would it be rude to do so? Can I do it anonymously or can I maybe incorporate it into a teasing-style joke that maybe he would get the hint? Should I just keep quiet? I wish this kind of stuff didn't bug me so much, but it does.
