I had to urinate in a bottle more times than I can count, and I can say there is some weird satisfaction in doing so as you can see the amount and concentration, as well as it being super warm making great handwarmers in the winter and you don't have access to AC. That said, you and everyone with you quickly learn not to carry apple juice or lemonade as a beverage, and never trust an opened bottle, especially if you can't inspect the color of the contents in the dark.
I have no idea how a girl would do this without causing a huge mess though.
