Good ol' reliable 7-11.
No matter what American city you're in, where else can you get a shriveled up hot dog of questionable age, two piss warm bottles of Gatorade for $1.99, trip over a nodded-out junkie on the way into the store and be accosted by shirtless, bug-eyed tweakers demanding change and spare cigarettes on the way out...all at 3AM?
