Learn English – Some more polite ways to tell a stalker, or someone you don’t like, to go away

When you say:

Would you tell me the way to the station?

you are asking a favor of someone.

When you say:

Could you tell me the way to the station?

literally you are asking if the person knows the way to the station and can tell you. As a question it is implied that you are hoping for the answer, but permission or whether the person wishes to answer is not addressed.

As such, using would is more polite.

The first is more polite while the second is more impersonal and better suited to a corporate or institutional setting where the recipient might not have a relationship with the writer.

Both are however too wordy; the recipient knows you're informing her by the fact that you're sending her a message. 'Asked for' is also too colloquial for a business or academic setting. I'd use 'requested'.

Also, the word 'completed' is ambiguous and not idiomatic (it could mean that it's been scanned but not made available for download, for instance). I would suggest instead:

"The document you requested is ready for pickup."

or if it is to be downloaded,

"The document you requested is available for download at [URL]."

or if you're sending this message with a PDF or other electronic copy of the document,

"Please find enclosed XXXXXX, per your request."
