This happened a while ago.
I was driving and was held up in traffic and had a period disaster, tampon became saturated and soaked through to my clothes.
I parked at the next available filling station and asked to use the loo. The attendant refused, saying they had no public loos. I am not sure if he was aware of my predicament, he would have been as I walked away at any rate . I ended up meekly walking out, not wanting to draw further attention to myself, and eventually found a public loo on the street - one of those pod jobs. My clothes were still stained and wet and awful though. I wonder if I should have persisted in the filling station and insisted/asked for some understanding? There were a number of females in the queue, but they just looked a bit blank.
Was IBU?
