Muzique Says "No Fat Girls": Does Club Have Right to Discrimate?

(CBS) We are all constantly bombarded by messages to lose weight and get in shape, but one Montreal nightclub has taken to outright banning those who don't drop the pounds - at least for one night.
Last week, the Facebook page of Muzique posted an ad for a party that read  "NO FAT GIRLS ALLOWED!!!!!!!!!!," according to the Montreal Gazette.
The club's management claims it was meant as a joke and blamed the party promoters for posting it.
"We didn't even realize (the comment) was there until a couple of days ago, and it was too late to retract it because the event had already happened," John Jay, Muzique's press man, told the Gazette.
"We don't think it's funny at all."
Neither do some of the club's customers.
"When I saw it, I freaked out. I was livid," one plus-sized fan of the club told the paper.
"It's discrimination pure and simple and discrimination is wrong," Jeanette DePatie, spokeswoman for the Association for Size Diversity and Health told CBS News. "This isn't tolerated for most other disenfranchised groups anymore. And it's sad that this is still tolerated and in some circles approved of."
The offending line has been taken down from their Facebook page. But the club's message still seems clear.
The club is the "flagship for all things fabulous in Montreal's high-end party scene," the current page reads. "Attracting a bevy of models, actors and young financiers every weekend to experience Montreal's most extravagant and exclusive events for the mature and distinguished."
Still, Jason Tull, one of the owners, tells CBS News his club doesn't discriminate. "I don't care if you are purple," he says. "People are people."
Ironically,  Tull is overweight himself, clocking in at 6-feet tall and 260 pounds. But, the club man says he looks great in a suit.
