Maybe the requests are processed by a computer and engraved by a laser (I have no idea how engraving works, I'm just throwing this idea out there). In that case the person typing the request in should've left it blank. At the same time the company should have hired someone who would be supervising these requests in case of a misspelling, typo or this situation.
Edit: I just came back to this post and read the title. I'm an idiot.
