Can anyone spell? (And if they can't spell, can they at least use a spell checker?)

Empty store on Seymour Street, Vancouver, BC

Sign on empty store, Seymour Street, Vancouver, BC

Over the weekend I saw this downtown in Vancouver. (The empty store is a former Source/Radio Shack location, but that is another story.)

How hard is it to spell things correctly? If you going to the trouble of having signs printed, would it not make sense to ensure that the wording is accurate? Does the sign shop take a similar level of care to ensure that the telephone number is correct?

It just makes me want to weep.
