A Good Poker Face Is The Mark Of A Great Cashier

This was when the chip cards first came out. A particular bank would only allow their cards to be used as debit and not credit. I had to tell this lady three times she had to choose debit and put in her PIN. After about thirty seconds she said:

Customer: “I only know what my PIN is at the bank. Is it the same here?”

I smiled and said yes, but I had to fight extremely hard to keep from laughing until she walked out the door.
