As a bank customer
I want to be notified one hour after a failed contactless card payment
So that I ... know that I did the right thing by inserting the card without getting distracted by an instant notification I wouldn't read anyhow?

Okay, today I tried to stay as far away from the IDE as possible to escape the predicted off-by-one error. And then I arrived at the hotel.
