Well, you collected a bunch of things, and now suddenly the scanner stops working. You look around and suddenly you notice that there's nobody around. You could abandon the basket and go to another store, but that would take time and effort... Or you could "come back and pay tomorrow".
You are in a maze of twisty little passages, all alike.
those digits that start with 9
what, like '9' ?
Or "6" if you're standing on your head... Possibly "l" if you're a neighboring digit looking at your two-dimensional buddy on the same plane... Or if you're a surrealist, the answer could be "rutabega".
The solution of this problem is trivial and is left as an exercise for the reader.
