After waiting 20 minutes on hold, and a brief conversation about my ‘TFL issues’, the oyster card assistant lady says, “No, I think you’re getting confused. You have a student discount that expires on 14th October and then you have an annual zones 1-3 pass that expires on the 2nd October”. Sorry, little miss oyster card assistant lady, all I see in front of me is ONE oyster card with ONE expiry date. A glorious example of a mismatch between mental models of 2 users.
