You must ALWAYS keep your Telephone PIN secret.

You must NEVER tell anyone your PIN – not even your friends or the Bank workers.
You must also keep your Account Number, password and security details secret and safe.
You CAN tell the Bank worker your Account Number, Sort Code and security details, but you will only ever be asked for PART of your password, not all of it. You should NEVER be asked for the whole password.
If a Bank worker does ask you for your whole password, or if you are worried, DO NOT tell them. Afterwards tell your Bank what happened.
