More than 400000 of us for each of those locations then, and how many of us have then bothered to wander in, I wonder?
Anyway, would you really trust an American company to actually make their sandwiches 1ft tall?
How would you even start to eat such a thing?
(Also most standardized feet are around 30 cm, so 12ft is ~ 3.6 m)
It's a service.
It's a service given to you for free by a company with no apparant way of generating income.
Would you think about that, please?
