My favourite bank story is when, a few years back I went to Italy. I'd got a HSBC Credit Card and a HSBC Debit card, both linked to the same account. I wanted to use the Debit Card, ideally, but didn't know if it would work. Well, I tried to withdraw some cash on Day 1 and it came up with a message in Italian and wouldn't let me.
No drama, I used the Credit card for the next 8 days! As in, every single penny went on this credit card.
I got back home, went to get some Petrol and my debit card was declined! I called HSBC and they told me Fraud Protection had picked up an attempt to withdraw…
