Any gas station that sells Big Gulps and doesn't have a bathroom or a decent bush outside is inhumane.
Never use gas stations - only have a bike BUT........I have no problems pissing behind a tree, building or whatever if I'm caught short. My partner is a marvellous lookout! I only go behind stuff so as not to upset the more gentile members of public, I personally don't give a fuck who sees me pee.
big gulp is a drink so big it takes 2 people to carry it...its for people that dont give a shit what they put in their body...it comes out of a disgusting machine and is colored neon colors
