I work in an exclusively male environment, I have to get changed in the locker room which in itself doesn't bother me as I have only ever seen one bloke in there at the time I get into work so I just went round the corner. No problems. However yesterday I was in a hurry and I packed my bag quickly.
This morning I got into work and found three tampons (still wrapped!) neatly lined up on the bench outside my locker, 
I tell myself that these are all grown men, most of whom are married with children and clearly a working knowledge of the female reproductive system. They are all my patients though and I will definitely blush when I see them!
