> Another atrocity is an alert with a “don’t ask again” check box, especially in something that is unnecessarily-modal (read: developer was lazy). Pro tip: if you think the user won’t want to see your message ever again then you need to redesign your system to keep the message from appearing even the first time.

That one I think is rather sensible for permission requests from apps. "Do you want to share your location with this app? - Yes/No; [] don't ask again", where the tickbox serves to store the preference forever. An alternative would be "Yes, always"/"Only now"/"Not now but ask again later"/"Never". Not sure which one I’d prefer.
