An elderly man got angry at the bank and said: "Ten years ago, a bowl of beef noodles cost 4 yuan. I deposited 10,000 yuan in your bank, which is equivalent to 2,500 bowls of beef noodles. Now, beef noodles have risen to 10 yuan each. The 10,000 yuan I deposited, including interest, is only 13,500 yuan—enough to buy just 1,350 bowls of beef noodles! I just want to know where the other 1,150 bowls went."

The bank staff looked at each other, unsure how to respond.

At this moment, a young girl who had just started her internship said: "Grandpa, you've kept your money in our bank for so long. The bank staff are watching over your money; they don’t need to eat, do they? Can they look at your money with eyes that are starved and white? It’s perfectly normal for them to eat you a bowl of beef noodles every now and then!"

After hearing this, the elderly man thought it made a lot of sense and stopped causing a fuss.
