Do you work in a job where you can't stop the clock for 10 minutes to take care of bodily functions? The only choices here are between getting penalized for lateness, pissing in a bottle, or finding a new job, and they amount to the same thing - bottle or new job. Plus it's absolutely disgusting. I think if it were personal choice alone, people would be more discreet. This story implies they're so pressed for time they can't even toss the bottle in the trash because they have to refill it... I can't even begin to imagine how that becomes a normal everyday activity at a company without somebody questioning how things got this way.
You have no idea what was in the mind of the driver, but you're passing pretty strong judgement.

This is what it really comes down to - your victorian sensibilities about bodily fluids can't possibly imagine that anyone would gasp OMG pee in a bottle! unless the alternative is starvation or whippings.
There are plenty of people who don't feel this way. Hell, I'm sitting outside with a flush toilet less than 100 ft from me and I just pissed on a tree instead. It's just piss.
