That would require making eye-contact with the enemies who are also in the store.
Actually, the last time I went to the store there was a single line for all registers (good), but for a good 5 minutes it didn't move, presumably because of the incredibly loud, angry yelling coming from somewhere I couldn't see (bad).
Re: digital lists, most of the time it's easier for me because scratching stuff off and my wife orders lists in how she goes through the store which is some wacky-ass bullshit so I have to constantly scan it. Crossing out with a pen requires two hands, deleting from phone just one. Also she's often adding stuff as I leave. #organized.
Speaking of the store, we're on our last bag of rice so I think I'm going to take a quick ride down to the local mexican grocery, I've heard ethnic stores are way better supplied than the regular places, and if ANYONE in the goddamn town has some motherfucking black beans it's probably the Mexican grocers...
