Ok, which code do I write down?
Imagine
this scenario.
You get to the airport only half an hour before your
flight. You park your car in long term parking and see
the shuttle bus coming.
As you grab your bags, you
remember that you should write down where your car is
parked otherwise you won't be able to find it when
your return from
your trip. You look around and see
"F7" on the ground. Then you look over and
see "15" on a light pole! Then you look
over at the shuttle bus stop and it says "E".
Ok, so what code do I write down? "F7",
"15" or "E"?
Design suggestion
A person doesn't know which of the codes is important so a single simple coding scheme should be devised. You don't want people thinking "Is F7 specific enough or are there multiple F7s? Do I need to know both E and F7?"
