You can find some buildings in the US with no 13th floor.
I'd like to see one that starts on the 14th floor. I mean, if we're going to indulge arbitrary biases, let's go all-out.
And while we're at it, let's have at least a few cases where we number the ceilings, too.
He makes a fair point though--if you're so superstitious that you're uncomfortable with the thirteenth floor, shouldn't you be uncomfortable about it regardless of its nomenclature?
