That angle is a bit high to actually sweep up any dust, Kyouko...
Actually, you use a dustpan like that to help get it into a pile, then you sweep it up. Keeps it from going everywhere... you want to get as much into a pile first, then put it into the pan.
Have you ever used a broom?We're opening for the day!30 minutes later...Um, that's enough, already...You get all the rubbish into the dustpan like this.Very good, very good!
