Everywhere I've lived non-scheduled bus routes run like every 5-10 mins anyway.
Also, just walk for a bit? Or instead of doing a grocery trip pick some stuff up on the way home every day, one of the advantages of cities is usually, bus or walk, there's a grocery store on your commute home. Like you don't need to isolate every bit of your life.
Yeah. These giant stores are such repulsing places. It takes forever getting there, because they're placed outside of residential areas. And the place itself is hideous, a hostile desert landscape of carparks and giant oppressive concrete sarcophagi, dedicated to promoting mindless consumerism. No human being can thrive there. Even if you go but car, which is allegedly super-convenient, you have to walk a stupid long way just to get full your parking spot and into the store. Once you get inside there's a million people running around in there with oversized shopping carts. And the place is just too big on the inside. Did you forget to get apples before moving on to the napkin section? Congratulations, you just earned yourself a five minute walk back to where the apples are just because some psycho made the store too god damn big. And you always end up buying lots of useless crap you don't want because the place is made to manipulate you. Going there takes all day and drains all your energy.
