Your Friend Isn't Wrong
Raj put his money on the counter at the bank. “Good morning. I'm travelling next week, and I'd like to change some money, please.”
“Of course,” the teller said. “Where's your destination?”
“Japan. So I'll need yen, please.”
The teller checked her screen. “The exchange rate today is good for you. If you change it now, you'll get a little more than you would have last week.”
“That's good news,” Raj said. “Is there a charge for this?”
“Yes, there's a small charge for every exchange. It's three dollars, whatever amount you change.”
Raj thought for a moment. “So if I change all my money today, I only pay the charge once?”
“Exactly. If you come back twice, you'll pay it twice. It's more convenient to do it all now.”
“Then I'll change it all today,” Raj said. He handed over his money. “My friend told me the airport was easier.”
The teller smiled. “Your friend isn't wrong that it's convenient. But the airport rate is terrible. They said it was easy, but they didn't tell you it was expensive.”
Raj laughed. “He forgot that part.”
“They always do,” the teller said, counting out the yen. “Enjoy your trip.”
