Anyone who has visited the Casa Fuente Shop in the Forum Shops at Caesars Palace in Las Vegas has probably smoked a cigar on the popular patio out front. The Las Vegas smoking ban has threatened the patio privileges for those visiting the Fuente showcase store. The patio and store sit inside a mall where, according to the law, no smoking is allowed, but the patio is also part of the store itself, where smoking is permitted. Michael Frey, part owner of the Casa Fuente, sued this month to keep the patio open for smoking. "I am a cigar store", said Frey. "The law exempts cigar stores. so it does not matter that half the store is in the mall. I am exempt according to Nevada state law".
