A United Airlines flight had already taken off from London on its way San Francisco before realizing they'd forgotten to re-stock the only thing more important than tiny bottles of alcohol: toilet paper. So when the few rolls they had ran out, flight attendants offered passengers a complimentary downgrade to some cocktail napkins in a makeshift cardboard dispenser, shown above.
At least they chose the napkin stack sporting the slogan most appropriate to the conditions at hand. Though it'd be nice if they allowed passengers to make their own choice of improvised wiping materials. We're sure one or two people would have opted for torn up pages of SkyMall.
