I glanced gratefully at the woman. Once she had spoken up, others began to voice their opinions.

"Exactly! This old lady took someone else's seat and refused to get up. She wants to swap her second-class seat with a first-class one without paying the difference. Who does that?"

I pulled out my phone and showed her the payment code. "One hundred dollars. Let's round it down to ninety dollars. Transfer the money and you can have this seat."

"Why should I give you money? You young people should give up your seats for us. I'm honoring you by sitting in your seat! I wouldn't even want your seat on a train! You young people just want to be comfortable and have no respect for the elderly anymore."

She remained seated on the floor and I crouched down, holding my phone in front of her. I couldn't help but laugh hearing her words. "If you like comfort, why not try the business class seats? They're even better."

Her face darkened and she glared at me more fiercely. I became even more confident that she knew exactly what she was doing. Otherwise, she wouldn't have been looking around so cautiously when she boarded the train.
