The hack: Use a hand sanitizer to combat an oily face.

Does it work? I feel like a lot of dermatologists are shuddering at the prospect of someone putting Purell on their face. Do I recommend it? Not necessarily (I'll probably wake up tomorrow with flaky skin). But, it worked. In a pinch -- and I mean an absolute pinch where the horror of meeting someone with a greasy face far outweighs your revulsion at putting hand sanitizer on your face -- then yes, by all means go for it. It's a quick fix you probably have sitting in your purse right now. Still, you're probably better off grabbing a Starbucks napkin or toilet seat cover, which work just as well and won't dry out your skin.
