Supermarket king John Catsimatidis is threatening to shut down his entire Gristedes chain, according to the Post. Catsimatidis says he can’t pay the $3.5 million he owes to store workers after settling a lawsuit over unpaid wages and overtime. As the paper points out, though, he did manage to find over $1 million to pay for his daughter’s wedding to Richard Nixon’s grandson back in June. [NYP]
