Oh come the fuck on. Here's how easy it is to walk to a store and get groceries in a proper neighborhood: You just do. You get on your goddamn feet and you do it. Fucking idiot.
Even better you just use a bike. Boom. All the cargo space you need.
Most importantly: you go a few more times than once a goddamn month like you seem to imply, and you get less shit. Boom. 50 pounds of groceries my ass.
Hope the next time you slam your head into something, as you clearly have done many times, it makes you smarter rather than even more unbearably dumb.
