>>472106Sauce doesn't just mean where it originated, it can also be asking for a source the file can be obtained. This one is not available in /rs/, and OP may not know that. /rs/ doesn't seem to show stuff that has not been posted, nor should OP's feel obligated to check when they post sets. So, asking for sauce is a way to let them know without their having to look. What they do after that is up to them. That said, if possible a request for sauce should have a picture with it, even if it doesn't match the topic exactly.
