I've always admired the determination of delivery people to arrive on time at their destination. If you live in Seoul, you will no doubt count a great number of couriers on a motorcycle every few minutes, no matter which street or apartment building you may be at. They are available 24 hours a day, and it is not uncommon for people to be ordering a late-night snack at 4 am. It is a far more dangerous job than most think though, as they are expected to work in the snow or in the rain or in the hottest summer days, undeterred and determined.
