Money changers

I go to the bank to to buy some Japanese yen for my upcoming trip to Okinawa. I ask for 60,000 yen. The teller asks me how I would like it. "With a smile, please." I say.

"What denominations would you like it in?"

"Ten '6000's."

The teller growls at me.

"Sorry." I say. "I'm not from around here."

"How about ten '5000's and ten '1000's?" she suggests.

"Perfect!"

She counts it out, interspersing the different denominations, and hands it to me.

"Thank-you," I say. "Now how about that smile?"
