A pub in Sarnia, Ont., is being criticized after a woman who has multiple sclerosis was apparently denied entry over the weekend because the bouncers believed she was intoxicated.

In a Facebook message posted on Sunday, Mike Morgado said his wife was turned away from Ups N' Downs a day earlier because workers believed she was inebriated.

Morgado -- who was not with his wife at the time of the incident -- said her friends attempted to explain to the security guards several times that she suffers MS, but they were "incredibly rude."

"I am DISGUSTED by how you treated my wife…She wasn’t allowed to enter because you assumed she was intoxicated when in fact she suffers from multiple sclerosis," Morgado said. "I understand that it could appear so, but your behaviour after it was explained is despicable!"

The post has since been shared more than 1,400 times.

In response to Morgado's post, some commentators have said they will boycott the pub.

"I'll never set foot establishment again," Eirinn Em said. "Ignorance is no excuse period."

Ups N' Down owner John Mallon also responded to the post. He said the bouncers were "contracted security guards" from Hughes Intelligence, and not employees of his pub.

"I mention this, not as a feeble excuse (but) because I do take ownership of everything that transpires on my premises," Mallon said. He adds that he is a "big supporter of the MS Society," and he intends to watch security surveillance footage to review what happened on Saturday.

On Monday, Mallon told CP24 that he has reached out to the woman and her husband to apologize.

"I'd like to have dinner with them either here or somewhere else and work this out," Mallon said.

According to the security company, the woman was initially turned away on Saturday, but after the bouncers realized that she suffers from MS, they "reversed" the decision.

"When (her friend) told (the bouncers) the circumstances, security quickly reversed the decision," Steve Johnston, Hughes Intelligence security manager, told CP24. He adds that there was a short line at the time.

"The lady got upset and left… She was more than welcome at the establishment. She decided not to wait."

Johnston said they are "very sorry" for the incident, but denies that the security guards at the pub were rude to the woman.

"They are two my friendliest guys," he said.

He adds that guards saw the woman approach from another bar, and therefore assumed she had already been drinking that evening.

"She was helped up there by two other women, so security assumed she was intoxicated."
