I wonder whether it is an American thing to get lost in perfectly designed cities and spaces. Nothing can be further away from a Labyrinth than an IKEA store. Everything is mapped, logically arranged, signs and directions are posted everywhere, easier to navigate than a Walmart. They are huge, but huge fits America.
In all the countries I have been to, giving your address is enough. I noticed since I moved to the USA that besides giving my address I have to provide directions; and even so people get lost. GPS and smart phones have helped a lot, though.
