Having just moved houses into rural Korea, It was getting late and you've had a long day. The time was pressing 11pm, and you've yet to eat dinner. Finding your new fridge empty, asides from a solitary can of beer, you decide to order takeout. ...At this time of night, there was only one place still open within delivery distance.

It was dim sum place, with humble, decent ratings. You place an order, and expectedly, it takes longer than it should- given the downpour outside. However, you were starving, and it didn't help that it took nearly an hour for the knock to arrive at your door.

You open it to find a man, still donned in a bike helmet- drenched head to toe at your doorstep. He handed you your order after taking it out from his delivery bag. You take it- just wanting to satiate your hunger. Having pre-paid, you turn to close the door...

...When he catches it, and holds it open at a crack. The rain pitter patters off of his helmet.

"Excuse me, you haven't tipped."
