At noon, I was at McDonald's, and an elderly man next to me was standing in front of the self-order kiosk, raising his finger and then putting it down, back and forth several times.

A store clerk in his thirties saw this, but didn’t ask “Can I help you?” nor did he reach out to place the order for him.
He walked over, bent down, and pointed to the bottom right corner of the screen, saying, “Sir, look here, there’s a ‘Slow Order’ mode. Tap it, and it won’t rush you anymore.”
The elderly man was stunned for a moment, then placed his finger on that button.
A prompt popped up on the screen: You can take your time choosing, no rush.
The elderly man smiled and said, “This thing is pretty considerate.”
The clerk said, “It’s not the system that’s considerate, it’s the people who designed it.”
Then he turned around to clear the tables.
The elderly man stood in front of the screen, slowly flipping through each dish, like flipping through a new recipe book.
I was holding my tray and sitting nearby, suddenly feeling that the screen didn’t seem so cold anymore.
