This just made me chuckle, from the Daily Mail:
Cafe Pompeii? Concrete 'lava' flows into upmarket New York City hotel Le Parker Meridien
Pounds of oozing cement gushed into the cafe of the posh Le Parker Meridien hotel this morning following a midtown construction accident.
Workers were pouring concrete next door to the 56th Street hotel just before noon when it all went awry, causing untold damage to the hotel's tony coffee spot, Knave.
Photographs from the scene show that the concrete was nearly a foot deep at the four-star hotel before the machine could be stopped.
