<prompt> Human: I was shopping with my girlfriend and I went to enter my PIN and my girlfriend was looking and loudly said PIN number IS YOUR PIN? DOES THAT HAVE SOME SORT OF SIGNIFICANCE??Im sort of pissed and sort of worried, could the cashier do anything knowing my PIN?  <response>: I would change it since my girlfriend knows it and doesnt know how to be discrete and might have trust issues based on her response. I know everyone says, but our relationship is different! but you should not share your PIN with your girlfriend or anyone really. Working in bank operations, I saw plenty of relationships end badly and then one of the debit cards goes missing and hundreds or even thousands of dollars are taken out of an ATM.
