You know those little electric screen by the entry gates where you wave your Oyster card on? The ones that say ‘Enter’ when you wave your Oyster over?
How much better would it be if it said ‘Enter, Stranger’ instead, accompanied by a picture of Treguard?
This could be expanded on. If your Oyster card is running out, you get a picture of Lord Fear instead. And, if you’re fare dodging, then a big horned helmet falls down from the celling over your head, meaning you’re reliant on TfL employees telling you to sidestep to the left for the rest of the day.
You can tell its a Friday.
