Some years ago, I was traveling in S. Korea. I was crying at a bus station with a suitcase because I'd just received news that my grandma had died, while I was heading to the airport.

I was still crying when this student in middle school or high school (I knew because of her uniform) came to the bus stop. I knew it was a bit weird for a student to be out of school at that time, since it was around 12pm. But I didn't really care, and continued crying.

Finally, I settled down as the bus approached. I got up, and the student rushed past me to get on the bus before me. Okay, whatever. I just continued toward the bus, when the girl, who was already on the bus, helped me bring my suitcase onto the bus. I thanked her, thinking she was just doing a good deed.

Nope.

About 5 or 6 stops in (about 15 minutes), the bus driver asked me, "aren't you going to pay?" I was confused, since I definitely paid as I got on.

"No, Miss. I mean for your little sister. Aren't you going to pay for her?"

Shocked, I turned around to see if that girl was still on the bus.

Nope. She was gone.

Tl;dr: Some bitch pretended to be nice to me when I was upset so she could get out of paying the fare for the bus, leaving me to deal with it when she snuck off
