Same here... it would totally depend on what it was that got you into the situation.
Divorce etc., no problem, come on in, we've got plenty of good booze in the house.
If you were, say, covered in blood and asking to borrow the shovel, well then I'd have to insist you hosed off in the yard first--I'm very neurotic about stains.
In any case though, I have to admit I'm very leery of people wanting to stay for "a coupla days." I'd likely only go for one night, unless there were a very established deadline, like "my brother can wire me money as soon as he gets paid again" or "I'll surrender myself on Thursday, after I've seen the new South Park."
