Look, I don't blame the lady here, frankly she didn't even do anything that out of the ordinary. Sometimes you just have to go, it's happened to me before and when the situation arises you don't think you just act. I'm not proud of it (actually I am, they're still funny stories whenever they're told, except for one that's not true) but desperate situations call for desperate actions and this lady was desperate. Sure the store probably had a bathroom, and sure given the relatively small amount of piss involved here she in all likelihood could have held it but that's beside the point, and who are we to judge?
I do have a problem with her partner in crime here. What the fuck is he doing? Touching and sniffing the pee. That's way out side the responsibilities of a Public Pissing Decoy. Dude, your job is to get in, run a distraction and get out. You don't have to wallow, smell, and taste the piss. That's just disgusting.
PS: Yes I know this is like a week late, it got stuck at the bottom of my topics list.
