Spur of the moment -- my schedule is always changing. I know I need to go sometime during the week but it's totally going to depend on when I happen to have free time on the way home, and I generally won't know that until I'm heading home. It might be Tuesday, or it might not be till Friday.

Always having a bunch of bags on me just isn't a thing, not when you walk and take the subway everywhere and don't want to be lugging around a backpack when you go out for drinks and have nowhere to put it when you're standing around a bar.

I'll take the big bag when it's on the weekend and I'm making a special trip to the supermarket, but there isn't always an opportunity for that either.
