People usually fuck off when you make your best robot impression. Even the most persistent gnats will fuck off if you hint to them you don't want to be bothered.

That's the case for me anyways, things might be different depending on your local social etiquette.
I'm blessed to live in a culture where bothering people is frowned upon, so questions like that are unlikely to be asked in the first place. Since threads like this exist I suspect it's different in the US.
