Always keep an empty bottle or coffee cup in your vehicle at all times. Sometimes nature calls and you chose the wrong place to stop.
This happened to me a couple days ago. I stopped to get gas. The gas station was busy, almost every pump in use. The bathroom was ocupied. I had to piss.... bad..... I went back to my truck, fortunately I had an empty coffee cup. I used it while standing right next to my open door while acting like I am on the phone. Then I threw my coffee cup with the "left over coffee" into the trash can and drove away.
Shits and giggles.


Just like doing a UA, only without the faggot looking at you
