A DINER has gone into hiding after slamming restaurant staff on Facebook for tending to a woman having a heart attack instead of her on New Year’s Eve.

Holly Jones penned a misinformed tirade against Kilroy’s N’ Grill in the US state of Indiana, complaining that staff shunned her and that her $US700 “meal was ruined by watching a dead person being wheeled out from an overdose”.

“Every year we have come to Kilroys to enjoy New Years Eve and tonight we were screamed at and had the manager walk away from us while were trying to figure out our bill being messed up (sic),” Jones, a hairdresser who works at Serenity Salon in Indianapolis, wrote on Facebook.

“The manager also told us someone dying was more important then (sic) us being there making us feel like our business didn’t matter, but I guess allowing a junkie in the building to overdose on your property is more important than paying customers who are spending a lot of money.”

However, the “overdosing junkie” was actually a 57-year-old woman who had a heart attack during dinner with her husband, The Daily Mail reported.

Paramedics treated the woman, whose name has not been released, on the bar floor.

She is in a critical condition at IU Methodist Hospital in Indianapolis, according to a GoFundMe fundraising page set up by her daughter, Tohnna Wymer.

“When she does start to regain consciousness she will have a long road of recovery,” Wymer wrote.

“We fully believe in the power of prayer and know she will come back to us. She is a fighter and will fight to the end!”

The manager of the restaurant, Chris Burton, branded Jones “cold-hearted” in a scathing response that has gone viral on Facebook.

“We love feedback, whether it be positive or negative. I especially like feedback like this so others can see the disgusting people that we have to deal with sometimes,” Burton wrote.

“First of all, the ‘overdosing junkie’ that you speak of was a 70+ year old woman who had a heart attack. Thankfully she was finally revived at the hospital and survived. It sounds like you were very concerned about her so I thought you should know.

“But I can completely understand why you think being intoxicated a**holes that didn’t understand your bill should take priority over a human life. I especially appreciate you making your server (who doesn’t curse) cry as well. I’m sure she really enjoyed working on New Year’s Eve just to deal with people such as yourself.”

He also banned Jones from the restaurant.

People from all over the world sent positive messages to Burton, agreeing that Jones’s behaviour was “disgusting”.

Burton said one of the men who dined with Jones secretly gave staff extra tips to apologise for the hairdresser’s actions at the restaurant.

Jones has since deleted or deactivated her Facebook account, claiming that she had been hacked and didn’t write the offensive post.

Jones’ employer, Serenity Salon, has distanced itself from her.

“Serenity Salon is aware of the most recent negative publicity surrounding one of our Booth Rent Stylist,” salon staff wrote in a statement on Facebook.

“The posting to Kilroy’s Facebook page, allegedly by one of our Booth Rent Stylist, in no way represents the views of Serenity Salon or any of our staff. We are saddened by the events that took place that evening and will continue to pray for the women who suffered a heart attack at this establishment on New Year’s Eve. This was not a company event and no other persons from Serenity Salon were present.”
