Raised By A Single Mother, No Brothers, Never Dated

Dear Prudence,

I am one of five women at my office. Roughly three out of five mornings, the one man we work with spends the first 10 to 15 minutes of the day in the (single, shared) bathroom. We work in a small office where we need to be available to any current or potential clients who call or drop in, so it does affect the rest of us if someone disappears mysteriously since, obviously, he doesn't announce that he's heading off to the can. I feel that if something is happening on such a regular basis, he should be able to take care of it at home before he comes to work. (He has only a half-hour commute.) My two-part question for you is: Is it worth saying something to him about it? And, presumably this would be a job for our manager, but what would be the best way of going about this? She usually hasn't arrived by that point in the morning, and so is not aware of this tendency.
