When you have to go, you have to go. I lay my bag on the wall as I line up towards the urinal. I am grateful for the empty toilet and I unzip just as someone walks in. I curse under my breath as the man heads towards the urinals too, not a cubicle. Just to make this clear there are five other empty urinals but for reason he uses the one next to me. I tense and try to finish up. He just broke the unspoken rule of men's washrooms and I was about to yell at him to choose a different urinal but then stopped before I broke the other unspoken rule, which was the no talking policy.
I managed to clear out of there in a few seconds and then board my plane.
