Time to share an anecdote: I was once stuck in a traffic jam in a travel bus, for four hours, and discovered, only minutes before boarding the bus, that I absolutely needed to hit the bathroom.
Needless to say, this was a ride from hell. I genuinely fantasised of just using a bottle, but of course that wouldn't work with the other passengers being there.
I would have given almost anything to have a solution at that moment, lol. Men are too lucky as far as this is concerned, to just find a bunch of dense shrubs and do their business. Ugh. Give me that female urination device.
